It is narrated from Sayyiduna Abdullah bin Umar, may Allah be pleased with him, that when the Messenger of Allah, peace and blessings be upon him, raised his head from bowing in the Fajr prayer, he said: "Rabbana wa laka al-hamd." This was in the last rak'ah. Then he began to supplicate against certain people: "O Allah! Send Your curse upon so-and-so, ..." He supplicated against the hypocrites, but Allah the Exalted revealed this verse: (O Prophet!) You have no authority in the matter; Allah may accept their repentance or punish them, for they are wrongdoers.
