أسباب إجابة الدعاء وموانعه
Jābir (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: " No one should ask for anything by the face of Allah, except Paradise."  
عن جابر -رضي الله عنه- قال: قال رسول الله -صلى الله عليه وسلم-: «لا يُسْأَلُ بوَجْه الله إلا الجَنَّةُ».

شرح الحديث :


In this Hadīth, the Messenger of Allah (may Allah's peace and blessings be upon him) prohibited people from using the phrase “by the face of Allah” to request anything temporary and trivial of this world, because these are despicable and perishable while the face of Allah is great and eternal. However, the Prophet (may Allah's peace and blessings be upon him) permitted using this phrase to ask for Paradise or whatever leads to it, because Paradise is great and asking for it by Allah's face makes it even more prestigious and honorable.
