Allah knoweth what ye used to do secretly among yourselves ; but He turned to you and forgave you ; so now associate with them , and seek what Allah Hath ordained for you , and eat and drink , until the white thread of dawn appear to you distinct from its black thread ; then complete your fast Till the night appears ; but do not associate with your wives while ye are in retreat in the mosques . Those are Limits ( set by ) Allah : Approach not nigh thereto .
