وَلَا تُصَلِّ عَلَىٰٓ أَحَدٍۢ مِّنْهُم مَّاتَ أَبَدًۭا وَلَا تَقُمْ عَلَىٰ قَبْرِهِۦٓ ۖ إِنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَمَاتُوا۟ وَهُمْ فَٰسِقُونَ
And never (O Muhammad) pray for one of them who dieth, nor stand by his grave. Lo! they disbelieved in Allah and His messenger, and they died while they were evil-doers.
Surah At-Tawba(9:84)
Sahih al-Bukhari
Prayers (Salat)
Chapter: Whoever offered Salat (prayer)in a silk Farruj (an outer garment opened at the back) and then took it off.
Narrated `Uqba bin 'Amir:
The Prophet (ﷺ) was given a silken Farruj [??] as a present. He wore it while praying. When he had finished his prayer, he took it off violently as if with a strong aversion to it and said, "It is not the dress of Allah-fearing pious people."
