سُورَةُ المُجَادلَةِ

Do you, perchance, fear lest [you may be sinning if] you cannot offer up anything in charity on the occasion of your consultation [with the Apostle]? But if you fail to do it [for lack of opportunity], and God turns unto you in His mercy, remain but con­stant in prayer and render [no more than] the purify­ing dues, and [thus] pay heed unto God and His Apostle: for God is fully aware of all that you do.
