Narrated Abu Musa:

That he was in the company of the Prophet in one of the gardens of Medina and in the hand of the Prophet there was a stick, and he was striking (slowly) the water and the mud with it. A man came (at the gate of the garden) and asked permission to enter. The Prophet ﷺ said, "Open the gate for him and give him the glad tidings of entering Paradise. "I went, and behold! It was Abu Bakr. So I opened the gate for him and informed him of the glad tidings of entering Paradise. Then another man came and asked permission to enter. The Prophet ﷺ said, "Open the gate for him and give him the glad tidings of entering Paradise." Behold! It was 'Umar. So I opened the gate for him and gave him the glad tidings of entering Paradise. Then another man came and asked permission to enter. The Prophet was sitting in a leaning posture, so he sat up and said, "Open the gate for him and give him the glad tidings of entering Paradise with a calamity which will befall him or which will take place." I went, and behold ! It was Uthman. So I opened the gate for him and gave him the glad tidings of entering Paradise and also informed him of what the Prophet had said (about a calamity). 'Uthman said, "Allah Alone Whose Help I seek (against that calamity).

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ عُثْمَانَ بْنِ غِيَاثٍ، حَدَّثَنَا أَبُو عُثْمَانَ، عَنْ أَبِي مُوسَى، أَنَّهُ كَانَ مَعَ النَّبِيِّ ﷺ فِي حَائِطٍ مِنْ حِيطَانِ الْمَدِينَةِ، وَفِي يَدِ النَّبِيِّ ﷺ عُودٌ يَضْرِبُ بِهِ بَيْنَ الْمَاءِ وَالطِّينِ، فَجَاءَ رَجُلٌ يَسْتَفْتِحُ، فَقَالَ النَّبِيُّ ﷺ " افْتَحْ لَهُ وَبَشِّرْهُ بِالْجَنَّةِ ". فَذَهَبْتُ فَإِذَا أَبُو بَكْرٍ، فَفَتَحْتُ لَهُ وَبَشَّرْتُهُ بِالْجَنَّةِ، ثُمَّ اسْتَفْتَحَ رَجُلٌ آخَرُ فَقَالَ " افْتَحْ لَهُ وَبَشِّرْهُ بِالْجَنَّةِ ". فَإِذَا عُمَرُ، فَفَتَحْتُ لَهُ وَبَشَّرْتُهُ بِالْجَنَّةِ، ثُمَّ اسْتَفْتَحَ رَجُلٌ آخَرُ، وَكَانَ مُتَّكِئًا فَجَلَسَ فَقَالَ " افْتَحْ {لَهُ} وَبَشِّرْهُ بِالْجَنَّةِ، عَلَى بَلْوَى تُصِيبُهُ أَوْ تَكُونُ ". فَذَهَبْتُ فَإِذَا عُثْمَانُ، فَفَتَحْتُ لَهُ، وَبَشَّرْتُهُ بِالْجَنَّةِ، فَأَخْبَرْتُهُ بِالَّذِي قَالَ. قَالَ اللَّهُ الْمُسْتَعَانُ.
