According to majority of opinion ,it is disliked to form a second congregation in Masjid
Perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
The jurists differed regarding the ruling of forming a second congregation in the mosque. The first opinion is that it is disliked to form a second congregation in a mosque which has an appointed Imaam and a congregation. The evidence about this is that At-Tabaraani reported that the Prophet came from the suburbs of Madeenah in order to pray in the mosque but he found that the people have already prayed. So he returned to his home and prayed with his family. Since he did not pray in the mosque, this means that it is disliked to form a second congregation in the same mosque. In addition to this, saying that it is permissible to make another congregation in the mosque may decrease the first congregation in number, because, if people know that if they miss the first congregation they would join the second congregation, then they would not hasten or be keen to pray with the first congregation and there is harm in this, but if they know that there is only one congregation they would hasten to join it and hence this congregation will be bigger in number. The view that it is disliked to form a second congregation is the view of the majority of scholars.

Reciting Quran for the dead
The Hanbali scholars believe that the reward of reading Qur'an as well as the reward of any other act that makes the person nearer to Allah, such a reward if sent to a person - whether alive or dead - reaches them. Al Buhooty said in 'Kashshaf Al Qina'e': 'It is lawful that the Muslim performs any good act (that brings the person nearer to Allah) with the intention that its reward or part of it (that reward) reaches another dead or living Muslim. The latter benefits from this reward.'

Celebrating personal birthdays and Anniversaries
If you mean formally celebrating the likes of the birthday of Prophet Muhammad (peace be upon him) or Prophet Jesus (peace be upon him) as a devotional act, then this is clearly unlawful. Such festive days are newly contrived innovations that conflict with the dictates of Islamic Law.
Such rites are from the traditions of the People of the Book. They have a devotional purpose and are carried out seeking nearness to Allah. This is the reason I view such occasions to be unlawful and prohibited.
If, on the other hand, you mean celebrating personal birthdays, then this is something different, since it is not intended as a devotional act or an act of worship. Therefore, it is not as serious a matter.
Still, personally I tend to regard it as something disliked for people who are not already accustomed to celebrating this event in their culture, but do so merely to blindly ape cultural practices that are outside of their own experience and understanding.
All the same, birthday parties are not religious occasions and do not have an overtly religious cast to them.
A birthday party is not a festival of the nature of an `îd that is a general festive day for the entire community. It is merely a personal occasion that means nothing more than a remembrance of something dear. Therefore, it is permissible.
And Allah knows best.

Shaking hands with Both or Singe Hand
Al-Bukhârî comes with another chapter entitled “The Chapter of Clasping with Two Hands”. At least, this is how the chapter heading is given in most editions of Sahîh al-Bukhârî. In some editions it reads: “The Chapter of Clasping with the Hand”. (
http://sunnah.com/bukhari/79/39)
Under this chapter heading, there is only a single narration that pertains to the issue of handshaking. It states that Hamâd b. Zayd shook Ibn al-Mubârak’s hand by taking it with his two hands.
Al-Bukhârî does not mention under this chapter heading any hadîth attributed to the Prophet (peace be upon him) about shaking hands.
The matter is an open one. And Allah knows best.

Similarly, these are not innovations:
1. 2 or 3 Athans for Jumah Salah (Uthman (ra) (

2. Triple Talaq (Umar (ra)) (

3. 20 Rakaths Taraweeh (Umar(ra))
4. Qunooth in Fajr, (Ali (ra)

5. Increasing the area of Wudhu (Abu Huraira (ra) See:
http://ilm4all.blogspot.in/2016/01/removing-doubts-increasing-area-of.html)
There is nothing wrong with that, because the Messenger (blessings and peace of Allah be upon him) said: “I urge you to adhere to my Sunnah and the way of the Rightly Guided Caliphs; hold fast to it.” He (‘Uthmaan) was one of the Rightly Guided Caliphs, and the interest served by that is quite clear. Hence this was adopted by Ahl as-Sunnah wa’l-Jamaa‘ah, and they did not see anything wrong with it, because it was part of the practice of the Rightly Guided Caliphs ‘Uthmaan and ‘Ali and those of the Sahaabah who were present at that time (may Allah be pleased with them all).

On the authority of Abu Najeeh al-’Irbaad ibn Saariyah (may Allah be pleased with him) who said:
The Messenger of Allah (peace and blessings of Allah be upon him) gave us a sermon by which our hearts were filled with fear and tears came to our eyes. So we said, “O Messenger of Allah! It is as though this is a farewell sermon, so counsel us.” He (peace and blessings of Allah be upon him) said, “I counsel you to have taqwa (fear) of Allah, and to listen and obey [your leader], even if a slave were to become your ameer. Verily he among you who lives long will see great controversy, so you must keep to my Sunnah and to the Sunnah of the Khulafa ar-Rashideen (the rightly guided caliphs), those who guide to the right way. Cling to it stubbornly [literally: with your molar teeth]. Beware of newly invented matters [in the religion], for verily every bidah (innovation) is misguidance.”
عَنْ أَبِي نَجِيحٍ الْعِرْبَاضِ بْنِ سَارِيَةَ رَضِيَ اللهُ عَنْهُ قَالَ: "وَعَظَنَا رَسُولُ اللَّهِ صلى الله عليه و سلم مَوْعِظَةً وَجِلَتْ مِنْهَا الْقُلُوبُ، وَذَرَفَتْ مِنْهَا الْعُيُونُ، فَقُلْنَا: يَا رَسُولَ اللَّهِ! كَأَنَّهَا مَوْعِظَةُ مُوَدِّعٍ فَأَوْصِنَا، قَالَ: أُوصِيكُمْ بِتَقْوَى اللَّهِ، وَالسَّمْعِ وَالطَّاعَةِ وَإِنْ تَأَمَّرَ عَلَيْكُمْ عَبْدٌ، فَإِنَّهُ مَنْ يَعِشْ مِنْكُمْ فَسَيَرَى اخْتِلَافًا كَثِيرًا، فَعَلَيْكُمْ بِسُنَّتِي وَسُنَّةِ الْخُلَفَاءِ الرَّاشِدِينَ الْمَهْدِيينَ، عَضُّوا عَلَيْهَا بِالنَّوَاجِذِ، وَإِيَّاكُمْ وَمُحْدَثَاتِ الْأُمُورِ؛ فَإِنَّ كُلَّ بِدْعَةٍ ضَلَالَةٌ".

Sunan Ibn Majah
http://sunnah.com/urn/1300440
Ibn Taymiyyah (r) used to recite al-Fatihah repeatedly after Fajr all the way to sunrise every day. [Al-Aʿlām al-ʿAliyyah]
Du‘aa’ after the obligatory prayer is not Sunnah if that is done
raising the hands, whether that is done by the imam on his own, or the
individual worshipper on his own, or by both of them. Rather it is an
innovation (bid‘ah), because that is not reported from the Prophet
(blessings and peace of Allah be upon him) or from any of his Companions
(may Allah be pleased with them). As for offering du‘aa’ without that,
there is nothing wrong with it, because there are some hadeeths that
speak of that. End quote.
