A man said in anger "Allaah is not just," but later repented. What is the ruling on this?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.

Undoubtedly, this phrase constitutes disbelief and apostasy, and the person who said it must renew his Islam and faith. If the man repents and re-embraces Islam, it is hoped that he is forgiven by Allaah , Allaah Willing.

It must be noted that it is the way of Allaah to test His believers to check the strength of their faith and patience. Indeed a true believer will thank Allaah and be patient, whereas a hypocrite will despair. Allaah Says (what means):

• {Alif, Lam, Meem. Do the people think that they will be left to say, "We believe" and they will not be tried?} [Quran 29:1-2]

• {And of the people are some who say, "We believe in Allaah," but when one [of them] is harmed for [the cause of] Allaah, they consider the trial of the people as [if it were] the punishment of Allaah.} [Quran 29:10]

• {And of the people is he who worships Allaah on an edge. If he is touched by good, he is reassured by it; but if he is struck by trial, he turns on his face [to the other direction]. He has lost [this] world and the Hereafter. That is what is the manifest loss.} [Quran 22:11]

We ask Allaah to make us, this man and all the Muslims firm on Islam.
