Sahih (Sahih Muslim)
حَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبُو خَالِدٍ، - يَعْنِي الأَحْمَرَ - عَنْ سُلَيْمَانَ التَّيْمِيِّ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ " إِنَّ الْفَجْرَ لَيْسَ الَّذِي يَقُولُ هَكَذَا " . وَجَمَعَ أَصَابِعَهُ ثُمَّ نَكَسَهَا إِلَى الأَرْضِ " وَلَكِنِ الَّذِي يَقُولُ هَكَذَا " . وَوَضَعَ الْمُسَبِّحَةَ عَلَى الْمُسَبِّحَةِ وَمَدَّ يَدَيْهِ .
This hadith has been narrated by Sulaiman al-Taimi with the same chain of transmitters (but with a slight variation of words) that he (the Holy Prophet) said:The dawn is not like it as it is said; he then gathered his fingers and lowered them. But he said, it is like this (and he placed the index finger upon the other one and spread his hand)
