حَدَّثَنَا أَبُو بَكْرٍ النَّيْسَابُورِيُّ ، ثنا عَلِيُّ بْنُ سَعِيدِ بْنِ جَرِيرٍ ، ثنا سَهْلُ بْنُ بَكَّارٍ ، ثنا مُحَمَّدُ بْنُ عَبْدِ الْعَزِيزِ ، عَنْ أَبِيهِ ، عَنْ طَلْحَةَ ، قَالَ : أَرْسَلَنِي مَرْوَانُ إِلَى ابْنِ عَبَّاسٍ أَسْأَلُهُ عَنْ سُنَّةِ الاسْتِسْقَاءِ ، فَقَالَ : " سُنَّةُ الاسْتِسْقَاءِ سُنَّةُ الصَّلاةِ فِي الْعِيدَيْنِ ، إِلا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَلَبَ رِدَاءَهُ فَجَعَلَ يَمِينَهُ عَلَى يَسَارِهِ وَيَسَارَهُ عَلَى يَمِينِهِ ، وَصَلَّى رَكْعَتَيْنِ وَكَبَّرَ فِي الأُولَى سَبْعَ تَكْبِيرَاتٍ ، وَقَرَأَ : سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى ، وَقَرَأَ فِي الثَّانِيَةِ : هَلْ أَتَاكَ حَدِيثُ الْغَاشِيَةِ ، وَكَبَّرَ فِيهَا خَمْسَ تَكْبِيرَاتٍ " .
Talhah (may Allah have mercy on him) narrates: Marwan sent me to Abdullah bin Abbas (may Allah be pleased with them both) so that I could ask him about the Sunnah method of the prayer for rain (Salat al-Istisqa). Abdullah bin Abbas (may Allah be pleased with them both) said: The Sunnah for Istisqa (i.e., supplicating for rain) is that the prayer for rain should be performed in the Eid ground. However, the Prophet Muhammad (peace and blessings be upon him) had turned his cloak inside out. He (peace be upon him) placed its right side on the left and its left side on the right. He (peace be upon him) performed two rak‘ahs of prayer. In the first rak‘ah, he (peace be upon him) said the takbir seven times and recited Surah al-A‘la, while in the second rak‘ah he recited Surah al-Ghashiyah. In the second rak‘ah, he (peace be upon him) said the takbir five times.
