«قال الله تعالى: لا يأتي ابن آدم النذر بشيء لم أكن قد قدرته ولكن يلقيه النذر إلى القدر وقد قدرته له استخرج به من البخيل فيؤتيني عليه ما لم يكن يؤتيني من قبل!»
The Prophet (peace and blessings be upon him) said:
"Allah Almighty says: The vow does not bring the son of Adam anything that I had not already decreed; rather, the vow leads him to the decree that I had already written for him. Through it I extract (wealth) from the miser, so he gives Me for it what he would not give Me before."
