Praying: "O my Lord! infirm indeed are my bones, and the hair of my head doth glisten with grey: but never am I unblest, O my Lord, in my prayer to Thee!
When My servants ask thee concerning Me, I am indeed close (to them): I listen to the prayer of every suppliant when he calleth on Me: Let them also, with a will, Listen to My call, and believe in Me: That they may walk in the right way.
Of their goods, take alms, that so thou mightest purify and sanctify them; and pray on their behalf. Verily thy prayers are a source of security for them: And Allah is One Who heareth and knoweth.
