Hadith 1412
نَا مُحَمَّدُ بْنُ يَحْيَى ، حَدَّثَنَا حَجَّاجٌ ، حَدَّثَنَا حَمَّادٌ ، عَنْ ثَابِتٍ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " اسْتَسْقَى هَكَذَا ، وَمَدَّ يَدَيْهِ ، وَجَعَلَ بَاطِنَهَا مَا يَلِي الأَرْضَ حَتَّى رَأَيْتُ بَيَاضَ إِبْطَيْهِ "
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) made the supplication for rain (du'a al-istisqa) in such a way that he spread out both his hands, and their palms were facing towards the ground, until I saw the whiteness of his armpits.
