Abomination of saying: "What Allah Wills and so-and-so Wills"
1745. Hudhaifah bin Yaman (May Allah be pleased with him) said: The Prophet (PBUH) said, "Say not: `What Allah wills and so-and-so wills', but say: `What Allah wills, and then what so-and-so wills.'''
[Abu Dawud with authentic Isnad].
Commentary: The first form mentioned in this Hadith is prohibited for the reason that it combines the will of someone with the Will of Allah, which is utterly wrong and against the factual position. In the second form, the Will of Allah comes first, which is the correct position, and the will of someone else comes later which is subject to the Will of Allah. The later form is quite fair.
It is as if someone says to a person, "I have only Allah's Support and yours''. In this statement Allah and man (the person addressed) are given the same status, which is most unfair and unjust. It would, however, be all right to say "We have the support of Allah and then yours'', because this statement does not have any trace of Shirk, which the former statement has.
