[Machine] "The sunnah of seeking rain refers to the sunnah of performing prayer on the two Eids, except that the Messenger of Allah ﷺ turned his cloak inside out and placed his right over his left and his left over his right and prayed the two units of prayer. He magnified during the first unit with seven takbeerat and recited "Subhan Allahi-l-A'la" and recited "Hal ataaka hadithu-l-ghashiya" in the second unit, and magnified it with five takbeerat."  

الحاكم:١٢١٧ – حَدَّثَنِي عَلِيُّ بْنُ حَمْشَاذَ الْعَدْلُ ثنا هِشَامُ بْنُ عَلِيٍّ السَّدُوسِيُّ حَدَّثَنِي سَهْلُ بْنُ بَكَّارٍ ثنا مُحَمَّدُ بْنُ عَبْدِ الْعَزِيزِ بْنِ عَبْدِ الْمَلِكِ عَنْ أَبِيهِ عَنْ طَلْحَةَ بْنِ يَحْيَى قَالَ أَرْسَلَنِي مَرْوَانُ إِلَى ابْنِ عَبَّاسٍ أَسْأَلُهُ عَنْ سُنَّةِ الِاسْتِسْقَاءِ فَقَالَ

«سُنَّةُ الِاسْتِسْقَاءِ سُنَّةُ الصَّلَاةِ فِي الْعِيدَيْنِ إِلَّا أَنَّ رَسُولَ اللَّهِ ﷺ قَلَبَ رِدَاءَهُ فَجَعَلَ يَمِينَهُ عَلَى يَسَارِهِ وَيَسَارَهُ عَلَى يَمِينِهِ فَصَلَّى الرَّكْعَتَيْنِ يُكَبِّرُ فِي الْأُولَى سَبْعَ تَكْبِيرَاتٍ وَقَرَأَ سَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقَرَأَ فِي الثَّانِيَةِ هَلْ أَتَاكَ حَدِيثُ الْغَاشِيَةِ وَكَبَّرَ فِيهَا خَمْسَ تَكْبِيرَاتٍ»  

هَذَا حَدِيثٌ صَحِيحُ الْإِسْنَادِ وَلَمْ يُخَرِّجَاهُ

[Machine] That the Messenger of Allah ﷺ draped his cloak over his left shoulder, placing his right hand on his left hand, and performed the two Rak'ahs. He invoked Takbir seven times in the first Rak'ah, recited "Subhanaka Allahumma wa bihamdika" (Glory be to You, O Allah, and praise be to You) and recited Surah Al-A'la (The Most High). In the second Rak'ah, he invoked Takbir five times.

أَنَّ رَسُولَ اللهِ ﷺ قَلَبُ رِدَاءَهُ فَجَعَلَ يَمِينَهُ عَلَى يَسَارِهِ وَيَسَارَهُ عَلَى يَمِينِهِ وَصَلَّى الرَّكْعَتَيْنِ فَكَبَّرَ فِي الْأُولَى بِسَبْعِ تَكْبِيرَاتٍ وَقَرَأَ بِ سَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقَرَأَ فِي الثَّانِيَةِ هَلْ أَتَاكَ حَدِيثُ الْغَاشِيَةِ وَكَبَّرَ فِيهَا خَمْسَ تَكْبِيرَاتٍ
