Ibn Jurayj narrated that I asked Ata: "Have you seen any of the Companions of the Messenger of Allah (ﷺ), may Allah be pleased with them, kiss their hands when they performed istilam?" Ata said: "Yes, I saw Jabir bin Abdullah, Ibn Umar, Abu Sa'id al-Khudri, and Abu Hurairah, may Allah be pleased with them, that when they performed istilam, they also kissed their hands." Ibn Jurayj said: "And Ibn Abbas as well?" Ata said: "Yes, and I think I saw many more." Ibn Jurayj said: "Do you not kiss your hands when you perform istilam?" He said: "(Yes,) but now I do not kiss them."
