This theme first gathers the verses in which Allah is witness over all things, then those that make the Messenger ﷺ a witness over his community and the community a witness over mankind. It also covers the rules of testimony: not concealing it, testifying only to what one knows, requiring an upright witness, rejecting false testimony, and the witnesses required in cases of slanderous accusation.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
And test the orphans [in their abilities] until they reach marriageable age. Then if you perceive in them sound judgement, release their property to them. And do not consume it excessively and quickly, [anticipating] that they will grow up. And whoever, [when acting as guardian], is self-sufficient should refrain [from taking a fee]; and whoever is poor - let him take according to what is acceptable. Then when you release their property to them, bring witnesses upon them. And sufficient is Allāh as Accountant.
