عَنْ أَبِي سَعِيدٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَا مِنْ مُسْلِمٍ يَدْعُو بِدَعْوَةٍ لَيْسَ فِيهَا إِثْمٌ وَلَا قَطِيعَةُ رَحِمٍ إِلَّا أَعْطَاهُ اللَّهُ بِهَا إِحْدَى ثَلَاثٍ إِمَّا أَنْ تُعَجَّلَ لَهُ دَعْوَتُهُ وَإِمَّا أَنْ يَدَّخِرَهَا لَهُ فِي الْآخِرَةِ وَإِمَّا أَنْ يَصْرِفَ عَنْهُ مِنَ السُّوءِ مِثْلَهَا قَالُوا إِذًا نُكْثِرُ قَالَ اللَّهُ أَكْثَرُ
It is narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When a Muslim makes a supplication in which there is nothing sinful or anything involving breaking ties of kinship, Allah Almighty grants him one of three things: either his supplication is quickly accepted, or it is stored for him for the Hereafter, or an evil equal to it is averted from him. The Companions said: Then we will make many supplications. He (peace and blessings be upon him) said: Allah is even more generous.
