Qur'an 33:51

۞ تُرْجِى مَن تَشَآءُ مِنْهُنَّ وَتُـْٔوِىٓ إِلَيْكَ مَن تَشَآءُ ۖ وَمَنِ ٱبْتَغَيْتَ مِمَّنْ عَزَلْتَ فَلَا جُنَاحَ عَلَيْكَ ۚ ذَٰلِكَ أَدْنَىٰٓ أَن تَقَرَّ أَعْيُنُهُنَّ وَلَا يَحْزَنَّ وَيَرْضَيْنَ بِمَآ ءَاتَيْتَهُنَّ كُلُّهُنَّ ۚ وَٱللَّهُ يَعْلَمُ مَا فِى قُلُوبِكُمْ ۚ وَكَانَ ٱللَّهُ عَلِيمًا حَلِيمًا

Thou canst defer whom thou wilt of them and receive unto thee whom thou wilt, and whomsoever thou desirest of those whom thou hast set aside (temporarily), it is no sin for thee (to receive her again); that is better; that they may be comforted and not grieve, and may all be pleased with what thou givest them. Allah knoweth what is in your hearts (O men), and Allah is ever Forgiving, Clement.
