A man thinking to himself of divorcing his wife

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty has pardoned my Ummah the thoughts of their hearts, as long as they do not speak of them or act upon them."

Ibn Sirin (may Allah have mercy on him) and al-Hasan (may Allah have mercy on him) said: Divorcing in one's heart is nothing.

Ibn Sirin (may Allah have mercy on him) said: Had he not asked (about it), that would have been dearer to me.

Isma'il bin Adam (may Allah have mercy on him) said: I asked Muhammad bin Sirin (may Allah have mercy on him): If a man divorces his wife in his heart, what is the ruling? He said: What is said within oneself is of no account.

The same is reported from Sa'id bin Jubayr (may Allah have mercy on him).

Jabir bin Zayd (may Allah have mercy on him) and Ata (may Allah have mercy on him) said: A divorce given in the heart is of no account.

(And from Ata:) They both (Jabir bin Zayd and Ata) said: It is nothing.

The same is reported from Ata (may Allah have mercy on him).

Something similar is reported from Jabir bin Zayd.

Amir (al-Sha'bi) said: If a man pronounces divorce or sets (a slave) free in his heart, it carries no weight.
