A Letter from Umar Radhiyallahu Anhu - Warning about alcoholic perfumes

بِسۡمِ ٱللَّهِ ٱلرَّحۡمَٰنِ ٱلرَّحِيمِ

According to al-Sari—Shu'ayb—Sayf—Abu al-Mujalid: 

The news reached 'Umar that Khalid once entered the bathhouse where, after he had removed the depilatory agent, he rubbed himself with a thick mixture of safflower(363) and wine

Caliph Umar (RA) wrote to him, saying, "It has reached me that you rubbed your body with wine; but God has forbidden the drinking  of wine or its use in any other way just as He has forbidden sins(364) 

committed in a direct or indirect manner. He has even forbidden the touching of wine unless you cleanse yourself of it immediately, just as He has forbidden you to drink it. So make sure it will 

not touch your body, for it is filth (365). And if you are actually still practicing this, (stop doing it immediately and) do not do it again!" Thereupon Khalid wrote to 'Umar, "We have diluted the 

wine with so much water that it is no longer wine but has become (ordinary) washing water(366)." Then 'Umar wrote to him, "I fear that the the descendants of al-Mughirah (367) have picked up 

some bad manners, but I pray that God will not destroy you for this." This last letter finally reached Khalid. 

363. Carthamus tmctorius, a dye used to achieve an orange-red color. 

364. The Arabic word used is ithm, which also means "wine" as well as "game 

of hazard." Perhaps a double entendre is intended here. 

365. The use of "filth" m this context seems to imply that touching it causes a 

person to incur a state of ritual impurity. 

366. For "diluting wine" Arabic uses the verb "to kill." 

367. That is, al-Mughirah b. 'Abdallah b. 'Umar, who was Khahd's grandfather 

and the eponym of a major subclan of the Makhzum clan of Quraysh. Caskel, 

pedigrees 22, 23. See also El 2 , s.v. Makhzum (Hinds).

Benefits from this letter
If we search for fatwas on alcoholic perfumes, we will get a ton of them that is it permissible. But if it comes to what is safe for religion, it would be best to try to avoid if possible. Here is a nice example for one of the hadiths from Sahih Bukhari on safer side. 
Imam Bukhari's Statement "To be on Safe side"
While discussing if thigh is part of Awrah, Imam Bukhari in his Sahih Bukhari says
وَحَدِيثُ أَنَسٍ أَسْنَدُ، وَحَدِيثُ جَرْهَدٍ أَحْوَطُ حَتَّى يُخْرَجَ مِنِ اخْتِلاَفِهِمْ .
Hadith of Anas is stronger according to Narration but Hadith of Jarhad is more safer for religion.
[Sahih Bukhari Book of Prayers (Salat) Chapter 12 Hadith 371]

A Letter from Umar Radhiyallahu Anhu - When Gentle Words Led to Repentance

بِسۡمِ ٱللَّهِ ٱلرَّحۡمَٰنِ ٱلرَّحِيمِ

The Transformative Effect of These Verses and a Wise Directive of Sayyidnā ʿUmar (رضي الله عنه)

This appears in the story 
Ibn Kathīr reports, on the authority of Ibn Abī Ḥātim, that there was a man from Syria who possessed a strong and dignified presence and who would regularly visit Sayyidnā ʿUmar (رضي الله عنه). When he failed to appear for a longer-than-usual period, Sayyidnā ʿUmar (رضي الله عنه) asked about him. The people replied, “O Commander of the Believers, do not ask about him. He has become addicted to drinking.”

Upon hearing this, Sayyidnā ʿUmar (رضي الله عنه) summoned his scribe and dictated a letter, saying:

من عمر بن الخطاب الی فلان بن فلان ۔ سلام علیک فانی احمد الیک اللہ الذی لا اَلٰہ اَلِّا ھو غافر الذَّنب و قابل التَّوب شدید العقاب ذی الطول لَا اِلٰہَ اِلَّا ھُو اِلَیہِ المَصیرُ ۔

“From ʿUmar ibn al-Khaṭṭāb to so-and-so, son of so-and-so.
Peace be upon you.
After this, I praise Allah before you—there is no deity worthy of worship except Him. He is the One who forgives sins and accepts repentance, the One who is severe in punishment, and the Possessor of all power. There is no god but He, and to Him is the final return.”

After dictating the letter, Sayyidnā ʿUmar (رضي الله عنه) turned to those present and said, “Let us all pray that Allah Most High turns his heart back and accepts his repentance.”

He further instructed the messenger not to deliver the letter until the man was sober, and not to give it to anyone other than the intended recipient.

When the man finally received the letter, he read it again and again with deep reflection. He realized that it contained both a warning of punishment and a promise of forgiveness. Overcome with emotion, he began to weep. He then gave up drinking entirely and repented so sincerely that he never returned to it again.

When Sayyidnā ʿUmar (رضي الله عنه) learned of the powerful effect of these words, he said to those around him:

“In such situations, you should act in the same way. When a brother slips into wrongdoing, think of how to bring him back to what is right. Encourage him to turn to Allah, to place his trust in Him, and to rely on His mercy. Pray for him—pray that he is enabled to repent sincerely. And do not become an ally of Shayṭān against him. For if you scold him harshly or drive him away, you will only be helping Shayṭān by distancing him from his faith.”

(Reported by Ibn Kathīr)
