الطبراني:٩٢٧١حَدَّثَنَا مُحَمَّدُ بْنُ النَّضْرِ الْأَزْدِيُّ ثنا مُعَاوِيَةُ بْنُ عَمْرٍو ثنا زَائِدَةُ عَنْ أَبِي إِسْحَاقَ عَنْ أَبِي الْأَحْوَصِ عَنْ عَبْدِ اللهِ قَالَ

«تَحْرِيمُ الصَّلَاةِ التَّكْبِيرُ وَتَحْلِيلُهَا التَّسْلِيمُ وَإِذَا سَلَّمْتَ فَعَجَلَتْ بِكَ حَاجَةٌ فَانْطَلِقْ قَبْلَ أَنْ يُقْبِلَ بِوَجْهِهِ»
