response to the oath. For this reason, it is not appropriate to say, 'By Allah, I will do,' nor 'By Allah, I will do.' It is only valid in the case of the letter 'ta' (ta' al-qasam, as in 'tallahi'), because it is not exclusively for swearing; therefore, it indicates that it is a request, and thus no expiation is due for it (38).
Section: It is established that the Prophet (peace and blessings of Allah be upon him) commanded the fulfillment of an oath (39). This was narrated by al-Bukhari (40). This, and Allah knows best, is by way of recommendation, not by way of obligation. The evidence for this is that Abu Bakr said, 'I swear to you, O Messenger of Allah, that you will inform me of what I was correct in and what I erred in.' The Prophet (peace and blessings of Allah be upon him) said, 'Do not swear, O Abu Bakr,' and he did not inform him (41). If fulfilling it were mandatory for him, he would have informed him. It is possible that it is obligatory for him to fulfill it when there is no harm in it, and the refusal of the Prophet (peace and blessings of Allah be upon him) to fulfill the oath of Abu Bakr was due to the harm he knew was in it. If he responds to the form of what he swore upon, rather than its meaning, when the meaning is unattainable, then that is good. It was narrated from the Prophet (peace and blessings of Allah be upon him) that al-Abbas brought a man to him to pledge allegiance for migration, but the Prophet (peace and blessings of Allah be upon him) said, 'There is no migration after the Conquest.' Al-Abbas said (42), 'I swear to you, O Messenger of Allah, that you will accept his pledge.' So the Prophet (peace and blessings of Allah be upon him) placed his hand in his hand and said, 'I have fulfilled the oath of my uncle, but there is no migration' (43). Thus, he responded to the form of the pledge, but not to what he had intended by his oath.
