خَاتَمَ النَّبِيِّينَ
The seal and final one of the prophets.
A new claim to prophethood after the Messenger ﷺ is not valid. The finality of prophethood includes the ending of the prophetic succession and the completion of its rank.
His message is not restricted to one nation or region; its call extends to humanity and jinn. Affirming earlier prophets and the finality of Muhammad's ﷺ prophethood are not competing beliefs; both belong to faith in the messengers.
