The Ruling on the Imam’s Supplication After the Prayers and the Congregation’s Response of Amine

His final question: Some people say that supplication is obligatory, meaning that the imam supplicates and the worshippers say "Amine." Is this correct or not?
Answer: Supplication is prescribed, not obligatory, but it is prescribed. A person supplicates in his prayer and outside of his prayer; he calls upon Allah and strives in good, asking his Lord for forgiveness, mercy, and the rectification of intention and deeds. He asks his Lord for lawful provision, a good wife, and righteous offspring. He asks his Lord for entering Paradise and being saved from the Fire, and so on. However, it is obligatory, according to a group of scholars, to say "My Lord, forgive me" between the two prostrations only, according to a group of scholars. As for the rest of the supplication, it is recommended. It is recommended to supplicate at the end of the prayer before saying the closing salam. It is recommended to supplicate in prostration. It is recommended to supplicate outside of the prayer and to ask his Lord for the good of this world and the Hereafter. All of this is recommended and sought after, but it is not obligatory.
As for what some people do of supplicating after the salam, where the imam supplicates after completing the obligatory prayer and they all raise their hands and say "Amine," this has no basis. This is from religious innovations. The Prophet (peace and blessings be upon him) and his Companions, when they said the salam, did not raise their hands and supplicate and say "Amine." No. If he wishes, the imam supplicates between himself and his Lord. The follower does the same. The Prophet (peace and blessings be upon him) used to supplicate after the prayer between himself and his Lord. As for the imam raising his hands and them raising their hands and supplicating together, with the imam supplicating and them saying "Amine," this has no basis and is not permissible. Rather, it is from the religious innovations that must be abandoned. However, a person supplicates for himself after the dhikr with what Allah has made easy, and the imam supplicates without contradicting this. The one who prays alone, if he missed the congregation for reasons, or because he is sick, or something similar, also supplicates between himself and his Lord. But the best is for it to be in his prayer, in prostration, before he says the salam. Because when the Messenger (peace be upon him) taught them the tashahhud, he said: meaning: before he says the salam. And he (may Allah’s prayer and peace be upon him) said: And he also (may Allah’s prayer and peace be upon him) said: .
Therefore, the believer should increase in supplication in his prostration, between the two prostrations, and at the end of the prayer before he says the salam. And if he supplicates after that, after the salam and after the dhikr, between himself and his Lord, there is no harm, without raising the hands and without supplicating with the imam. All of this has no basis. But he supplicates between himself and his Lord for himself only, without raising the hands after the obligatory prayer. And likewise after the voluntary prayers. And if he raises his hands at some times after the voluntary prayers, there is no harm. Or if he supplicates to his Lord at any time outside of prayer and raises his hands, all of this is sought after. Raising the hands is among the causes of acceptance. Yes.
