When the Prophet (peace and blessings be upon him) ordered 'Ali and Fatimah to pray, 'Ali said

The questioner : In the name of Allah.
The honorable Shaykh mentioned in the hadith the narration of 'Ali (may Allah be pleased with him) when the Prophet (peace and blessings be upon him) came to his door with Fatimah, and the Prophet (peace and blessings be upon him) said to them: The authentic hadith is that 'Ali (may Allah be pleased with him) cited the will of Allah as evidence, as it is well known that their souls are in the hand of Allah (Mighty and Majestic).
Ibn al-Qayyim says: "The argument of 'Ali (may Allah be pleased with him) is valid, and your eminence also said in the commentary on that in *Taqrib al-Tadmiriyyah*: 'And for that reason, the Prophet (peace and blessings be upon him) did not rebuke him.'"
So what is the reason for the Prophet (peace and blessings be upon him and his family) striking his thigh while he was going out reciting the words of Allah the Exalted: May Allah reward you with good?

The Shaykh : The reason for that is that it was more appropriate for 'Ali ibn Abi Talib (may Allah be pleased with him), when he said: not to argue in this way by citing divine decree, but rather to choose another expression that is better than this one. However, the Prophet (peace and blessings be upon him and his family) did not rebuke him when he cited divine decree. This indicates what was mentioned in *Taqrib al-Tadmiriyyah* that citing divine decree regarding something that has already passed is permissible, and the person, if it was a sin, should be repentant and seeking forgiveness, and if it was not a sin, such as leaving the night prayer, then he is leaving what is better. Yes.
