Prophet Isa (peace be upon him) and his companions came out of the city and into the deserts to pray for the rains. There he (peace be upon him) said to them: Those of yo, who have committed sins should return to the city. Hearing this instruction all of them returned back except one person. Turning to him, Isa (peace be upon him) said: Have you not committed any sin? He replied: I don’t remember having committed any except for one instance when, as I stood engaged in prayers, a lady passed by before me. I looked at her and my eyes continued to follow her. But as soon as she had left, I had thrust my finger into the eyes and, pulling it out, had thrown it in the direction where the lady had gone.
Isa (peace be upon him) said: Pray and I shall say Aameen. He prayed and the rains began to pour.( Shanidani-ha-e-Taareekh, pg. 22; Mahajjah al-Baidhaa, vol. 1, pg. 299. )
