And Allah said (in Surah At-Takwir): "You cannot will unless Allah wills." And (in Surah Aal-e-Imran) He said: "Allah grants kingdom to whom He wills." And (in Surah Al-Kahf) He said: "And do not say of anything, 'Indeed, I will do that tomorrow,' except [when adding] , 'If Allah wills.'" And (in Surah Al-Qasas) He said: "You cannot guide whom you love, but Allah guides whom He wills." Sa'id bin Al-Musayyib said from his father that this verse was revealed regarding Abu Talib. And (in Surah Al-Baqarah) He said: "Allah intends for you ease and does not intend for you hardship."

Narrated Anas: Allah's Apostle said, "Whenever anyone of you invoke Allah for something, he should be firm in his asking, and he should not say: 'If You wish, give me...' for none can compel Allah to do something against His Will."
