حَدَّثَنَا وَكِيعٌ حَدَّثَنَا سُفْيَانُ عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلٍ عَنْ مُحَمَّدِ ابْنِ الْحَنَفِيَّةِ عَنْ أَبِيهِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِفْتَاحُ الصَّلَاةِ الطُّهُورُ وَتَحْرِيمُهَا التَّكْبِيرُ وَتَحْلِيلُهَا التَّسْلِيمُ
مسند امام احمد بن حنبل · Hadith 1006
It was narrated from Muhammad Ibn al-Hanafiyyah that his father said: The Messenger of Allah (PBUH) said: "The key to prayer is purification; entering it is takbeer and exiting it is tasleem.”
