(حديث مرفوع) حَدَّثَنَا
سُفْيَانُ ، عَنْ
أَبِي أَيُّوبَ ، عَنْ
قَتَادَةَ ، عَنْ
أَنَسٍ ، قَالَ : " صَلَّيْتُ خَلْفَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَبِي بَكْرٍ ، وَعُمَرَ ، فَكَانُوا يَفْتَتِحُونَ بِ الْحَمْدُ " .
It is narrated from Hazrat Anas bin Malik (may Allah be pleased with him) that I have performed prayer with the Prophet (peace and blessings be upon him) and the three caliphs; these noble persons would begin the recitation in prayer with "Alhamdulillahi Rabbil 'Alamin."
