Verily he who is most persevering in the face of adversity is the most abstemious from among you.' Marry off those who are single among you and the upright ones from among your male slaves and your female slaves. If they are poor, Allah will enrich them out of His grace, and Allah is all-bounteous, allknowing: And of His signs is that he created for you mates from your own selves that you may take comfort in them, and He ordained a.ffection and mercy between you. There are indeed signs in that for a people who reflect.'
