The prayer of Istisqa’ (prayer for rain) was prescribed to ask for rain and water when it is absent or delayed beyond its usual time. In it, the Imam and the worshippers perform two Rak`ahs (units) with humility, seeking the Mercy of Allah - asking Allah to send down rain upon them.In this Hadith, `Abdullah ibn Zayd (may Allah be pleased with him) said: “The Messenger of Allah (peace and blessings of Allah be upon him) prayed the Istisqa’ prayer while wearing a Khamisah.” The Khamisah is a black, square piece of cloth made of wool or mixed fabric with stripes and markings. The narration reads that "The Prophet (peace and blessings of Allah be upon him) intended to lift the bottom part of it to make it reach higher," showing more humility and servitude to Allah (Glorified and Exalted is He). However, the narration continues, "when it became heavy, he folded it round on his shoulder". The shoulder here refers to the part of the body including the upper arm and the base of the neck. This means he placed what was on his right side to the left and what was on the left side to the right. If the garment had not been heavy, he would have flipped it completely, making its top side the bottom..
