And know that whatever thing you gain, a fifth of it is for Allah and for the Messenger and for the near of kin and the orphans and the needy and the wayfarer, if you believe in Allah and in that which We revealed to Our servant, on the day of distinction, the day on which the two parties met; and Allah has power over all things.

And if your Lord had pleased, surely all those who are in the earth would have believed, all of them; will you then force men till they become believers?

And even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.

Only those are believers who believe in Allah and His Messenger, and when they are with him on a momentous affair they go not away until they have asked his permission; surely they who ask your permission are they who believe in Allah and His Messenger; so when they ask your permission for some affair of theirs, give permission to whom you please of them and ask forgiveness for them from Allah; surely Allah is Forgiving, Merciful.
