This Hadīth clarifies the permissibility of supplicating during calamities. It is to be performed after rising from Rukū‘, according to the way the Prophet (may Allah's peace and blessings be upon him) did when Banu Sulaym broke the covenant between them and the Muslims by killing 40 or 70 of the reciters whom the Prophet had sent to them. The Prophet supplicated against them for a month after rising from Rukū‘.
