He asks: Is it permissible for me to say I love Umar more than Abu Bakr, or I love Uthman more than Umar, or I love Ali more than Uthman, or more than Abu Bakr, like this.
Yes, the basic principle.
The Blessed and Exalted, this is legislation, it is not permissible to love anyone alongside Allah.
Like the love of Allah, the Blessed and Exalted, as Allah, the Blessed and Exalted, says.
The verse: And among the people are those who take others besides Allah as equals, loving them as they should love Allah.
And those who have iman are stronger in their love for Allah. The love of Allah is not shared with anyone else.
And likewise, the love for the Messenger ﷺ. None of you truly believes until I am.
More beloved to him than his father, his child, and all people. Likewise, the Messenger ﷺ. As for the sahaba, may Allah be pleased with them, it is from the sunnah.
That we love all of them, and from the sunnah is that the love is according to how close he was to the Prophet.
ﷺ. As for saying that I love this companion more than that companion, inshaAllah there is no sin, but the sin is if you say so-and-so is better than so-and-so.
For example, whoever prefers any of the sahaba over Abu Bakr and Umar, the scholars have said he is an innovator.
Because there was consensus among them that Abu Bakr and Umar are the best of the Prophet's Companions.
ﷺ. The Prophet ﷺ was asked—Amr ibn al-As asked him: Who is the most beloved person to you? He said: Aisha. He said: And among the men? He said: Her father. He said: Then who? He said: Umar.
And Ali ibn Abi Talib, may Allah be pleased with him, when he said: Whoever prefers me over Abu Bakr and Umar, I will have him flogged with the punishment for slander.
And he is only punished for
a sin. Okay, he said: Whoever prefers me—so preference is one thing and love is
another. Meaning, you can say: For me, Abu Bakr is the best, but I love Umar.
More than that is wrong. But as for the matter of sin, this does not appear, and the knowledge is with Allah, the Blessed and Exalted.
