Afraid of what will fall into my heart...

Sa'eed ibn 'Aamir said, "I heard my grandfather, Ismaa'eel ibn Khaarijah speaking, saying, 'Two men from the People of Desires came to Muhammad ibn Seereen (d.110H) and said, 'O Aboo Bakr, can we narrate to you a hadeeth?' He said, 'No.' They said, 'Then can we recite an aayah to you?' He said, 'No. Either you stand (and leave) or I will stand (and leave).' So the two men stood and left. Some of the people said to him, 'What harm would it do to you if they recited an aayah?' He said, 'I disliked that they read an aayah to me and then distort it, so that this falls into my heart.'" [Ibid., no. 242]
