أَخْبَرَنَا مُحَمَّدُ بْنُ يُوسُفَ ، عَنْ سُفْيَانَ ، عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلٍ ، عَنْ مُحَمَّدِ بْنِ الْحَنَفِيَّةِ ، عَنْ عَلِيٍّ رَضِيَ اللهُ عَنْهُ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" مِفْتَاحُ الصَّلَاةِ الطُّهُورُ، وَتَحْرِيمُهَا التَّكْبِيرُ، وَتَحْلِيلُهَا التَّسْلِيمُ "
