Only Allah {SWT} knows

“Once someone said: By Allah! Allah {SWT} will not forgive such and such.” Thereupon Allah, the Exalted and the Glorious said: “Who is he who takes an oath in My Name that I will not grant pardon to so-and-so? I have granted pardon to so and so and rendered your good deeds fruitless.” {Muslim}

Usman ibn e Maz’oon was an immigrant from Mecca. He was living in the house of a Medinite, Ansar. He was treated hospitably as a member of the family, as that was the basic principle of the fraternal relations created by Holy Prophet {SAW} on immigration. 

He fell ill. Umme Ala Ansari, the woman of the house, was a pious Muslim. She nursed Usman with care, but his condition worsened and he died.

When the funeral was ready, the Holy Prophet {SAW} and Umme Ala pointed towards Usman’s funeral and said, “O Usman, may Allah’s blessings descend upon you. I testify that Allah {SWT} has granted you entrance into the realm of blessings.”

When the Holy Prophet {SAW} heard the statement, he asked her, “ How did you know that he had entered the realm of Allah’s blessings?” 

“I just said it. Obviously, I don’t know.” She replied.

“Usman ibn e Maz’oon has entered that realm where all veils are lifted from one’s eyes. I also wish him well, but I will like to add that even though I am a Prophet, I never express such an opinion about myself or anyone of you.”

Umme Ala never again passed such remarks on anyone’s funeral. She always said, “Only Allah {SWT} knows,” when asked for her opinion.

May Allah {SWT} protect us from error. Aameen.
