Sayyiduna ‘Ubada bin Samit (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Soon there will be rulers over you who will be so occupied with other matters that they will delay the prayers from their prescribed times. (In such a situation) you should perform the prayer at its proper time, and then consider the prayer you perform with them as a voluntary (nafl) prayer. A man asked: O Messenger of Allah! If I happen to pray with them, should I (pray again)? The Prophet (peace and blessings be upon him) said: If you wish (then do so).
