Arabic (Original)
حَدَّثَنَا عَلِيُّ بْنُ إِسْحَاقَ، أَنْبَأَنَا عَبْدُ اللَّهِ، أَنْبَأَنَا يَحْيَى بْنُ أَيُّوبَ، عَنْ عُبَيْدِ اللَّهِ بْنِ زَحْرٍ، عَنْ عَلِيِّ بْنِ يَزِيدَ، عَنِ الْقَاسِمِ، عَنْ أَبِي أُمَامَةَ، أَنَّ عَلِيَّ بْنَ أَبِي طَالِبٍ، رَضِيَ اللَّهُ عَنْهُ أَخْبَرَهُ أَنَّهُ، كَانَ يَأْتِي النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ فَكُنْتُ إِذَا وَجَدْتُهُ يُصَلِّي سَبَّحَ فَدَخَلْتُ وَإِذَا لَمْ يَكُنْ يُصَلِّي أَذِنَ.
English Translation
lt was narrated from Hadrat Abu Umamah that `Hadrat Ali bin Abi Talib (may Allah be well pleased with him) told him that he used to go to the Noble Prophet (blessings and peace of Allah be upon him). He said: If I found him praying, he would say tasbeeh and I would enter, and if he was not praying, he would give me permission to enter.
