حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدِ اللهِ، قَالَ‏:‏ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ‏:‏ إِذَا دَعَا أَحَدُكُمْ فَلاَ يَقُولُ‏:‏ إِنْ شِئْتَ، وَلْيَعْزِمِ الْمَسْأَلَةَ، وَلْيُعَظِّمِ الرَّغْبَةَ، فَإِنَّ اللَّهَ لاَ يَعْظُمُ عَلَيْهِ شَيْءٌ أَعْطَاهُ‏.‏

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "When one of you makes a supplication, he should not say, 'If you wish.' He should be firm in asking and he should have great hope. Allah does not think that anything that He gives is too great.'"
