Musnad Ahmad Hadith 19653

It is narrated from Abu Musa (may Allah be pleased with him) that once I was with the Noble Prophet (ﷺ) in a garden. A man came and greeted with salam. The Noble Prophet (ﷺ) said, "Go, give him permission to enter and also give him the glad tidings of Paradise." I went and found that it was Abu Bakr Siddiq (may Allah be pleased with him). I said to him, "Please come inside and accept the glad tidings of Paradise." He kept praising Allah continuously and sat down in a place. Then another man came and he also greeted with salam. The Noble Prophet (ﷺ) said, "Give him permission and glad tidings as well." I went and found that it was Umar (may Allah be pleased with him). I said to him, "Please come inside and accept the glad tidings of Paradise." He kept praising Allah continuously and sat down in a place. Then a third man came and he also greeted with salam. The Noble Prophet (ﷺ) said, "Go and give him permission as well, and give him the glad tidings of Paradise along with a trial." I went and found that it was Uthman (may Allah be pleased with him). And so it happened.
