THE QURA'NIC VERSES AND THE HADEES

عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ

  لاَ يَقُولَنَّ أَحَدُكُمُ اللَّهُمَّ اغْفِرْ لِي إِنْ شِئْتَ وَلْيَعْزِمْ فِي الْمَسْأَلَةِ فَإِنَّ اللَّهَ لاَ مُكْرِهَ لَهُ.‏‏

It was narrated from Abu Hurairah that the :

Messenger of Allah (saas) said: "No one among you should say: "O Allah, forgive me if You will.' Let him be definite in his asking, and no one can compel Allah." 

(Sunan Ibn Majah 3854)
