(قَوْلُ "اللَّهُ أَكْبَرُ" بَعْدَ الصَّلَاةِ)
(Saying "Allāhu Akbar" after prayer)
Hadith 959
عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: كُنْتُ أَعْرِفُ انْقِضَاءَ صَلَاةِ رَسُولِ اللَّهِ صَلَّى الله عَلَيْهِ وَسلم بِالتَّكْبِيرِ
Ibn ‘Abbas said he used to know that God’s Messenger had finished his prayer when he heard the takbir. (Bukhari and Muslim.)
