Abu Musa reported: The Messenger of Allah, peace and blessings be upon him, said, “Rejoice and give glad tidings that whoever honestly says there is no God but Allah will enter Paradise!” They went out and announced glad tidings to the people, and they were met by Umar, may Allah be pleased with him. They gave him glad tidings but he sent them back. The Prophet said, “Who sent you back?” They said, “Umar.” The Prophet said, “Why did you send them back, O Umar?” Umar said, “In that case, the people will take it for granted, O Messenger of Allah.”

عَنْ أَبِي مُوسَى أَنَّ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ أَبْشِرُوا وَبَشِّرُوا النَّاسَ مَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ صَادِقًا بِهَا دَخَلَ الْجَنَّةَ فَخَرَجُوا يُبَشِّرُونَ النَّاسَ فَلَقِيَهُمْ عُمَرُ رَضِيَ اللهُ عَنْهُ فَبَشَّرُوهُ فَرَدَّهُمْ فَقَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ مَنْ رَدَّكُمْ قَالُوا عُمَرُ قَالَ لِمَ رَدَدْتَهُمْ يَا عُمَرُ قَالَ إِذًا يَتَّكِلَ النَّاسُ يَا رَسُولَ اللهِ
