Fulfilling the Promise and the Hadith of the Sign of the Hypocrite

Question:
He says: It was mentioned in the lesson that fulfilling a promise is not obligatory according to the majority of scholars, so what is the guidance regarding the hadith of the Prophet (peace and blessings be upon him) that the sign of the hypocrite is four, and among them is that when he promises, he breaks his promise?

Answer:
The hypocrite does not perform the obligatory acts, nor does he perform the recommended acts; he shows indifference to acts of obedience, whether they are obligatory or recommended. The majority hold that fulfilling a promise is not obligatory, but Shaykh al-Islam and others chose that fulfilling a promise is obligatory, based on this hadith. The hadith that when he promises, he breaks his promise: breaking a promise is among the characteristics of the hypocrites. This indicates that fulfilling a promise is obligatory. Yes.
