حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي حَكِيمٍ، أَنَّ عَطَاءَ بْنَ يَسَارٍ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَبَّرَ فِي صَلاَةٍ مِنَ الصَّلَوَاتِ ثُمَّ أَشَارَ إِلَيْهِمْ بِيَدِهِ أَنِ امْكُثُوا فَذَهَبَ ثُمَّ رَجَعَ وَعَلَى جِلْدِهِ أَثَرُ الْمَاءِ ‏.‏

Yahya related to me from Malik from Ismail ibn Abi Hakim that Ataibn Yasar told him that the Messenger of Allah, may Allah bless himand grant him peace, said the takbir in one of the prayers and thenindicated to them with his hand to stay in place. He left and thenreturned with traces of water on his skin. Translation Not Available
