Verily, they only are believers who believe in God and His Apostle, and who, when they are with him upon any affair of common interest, depart not until they have sought his leave. Yes, they who ask leave of thee, are those who believe in God and His Apostle. And when they ask leave of Thee on account of any affairs of their own, then grant it to those of them whom thou wilt, and ask indulgence for them of God: for God is Indulgent, Merciful.
