It is narrated from Hazrat Ubayy bin Ka'b (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said to Hazrat Bilal (may Allah be pleased with him): "Bilal! Leave some interval between your adhan and iqamah so that during this interval, whoever is eating may finish his food, and whoever needs to perform ablution may finish relieving himself."

The previous hadith is also narrated through this second chain of transmission.

It is narrated from Hazrat Ubayy bin Ka'b (may Allah be pleased with him) that once on a Friday, the Noble Prophet (peace and blessings be upon him) recited Surah Bara'ah from the pulpit. At that time, the Noble Prophet (peace and blessings be upon him) was standing and mentioning the favors of Allah. Hazrat Ubayy bin Ka'b (may Allah be pleased with him) was sitting in front of the Noble Prophet (peace and blessings be upon him), and with him were Hazrat Abu Darda (may Allah be pleased with him) and Abu Dharr Ghifari (may Allah be pleased with him) also sitting. One of them pinched Hazrat Ubayy (may Allah be pleased with him) and said, "Ubayy! When was this Surah revealed? I am hearing it just now." Hazrat Ubayy bin Ka'b (may Allah be pleased with him) signaled him to remain silent. After the prayer was over, he said, "I had asked you when this Surah was revealed, so why did you not tell me?" Hazrat Ubayy (may Allah be pleased with him) replied, "Today your prayer is only as much as the vain act you did in it." He went to the Prophet (peace and blessings be upon him) and mentioned what Hazrat Ubayy (may Allah be pleased with him) had said, so the Prophet (peace and blessings be upon him) said, "Ubayy has spoken the truth."

It is narrated from Hazrat Ubayy bin Ka'b (may Allah be pleased with him) that the Prophet (peace and blessings be upon him), while describing the incident of Mi'raj, said: When I was in Makkah Mukarramah, one night the roof of my house was opened and Hazrat Jibreel (peace be upon him) descended. He split open my chest, washed it with the water of Zamzam, then brought a golden tray filled with faith and wisdom and poured it into my chest and closed it. Then he took my hand and took me to the heavens. When we reached the lowest heaven, he knocked on the door. Someone inside asked, "Who is it?" He replied, "Jibreel." He asked, "Is there anyone with you?" He replied, "Yes! Muhammad (peace and blessings be upon him) is with me." He asked, "Has he been called?" He replied, "Yes, open the door." When we reached there, a man appeared who had some people on his right and left. When he looked to his right, he smiled, and when he looked to his left, he began to weep. When he saw me, he said, "Welcome, O righteous Prophet and righteous son." I asked Jibreel (peace be upon him), "Who is he?" He replied, "This is Hazrat Adam (peace be upon him), and these people you see on his right and left are the souls of his children. Those on the right are the people of Paradise, and those on the left are the people of Hell." Then Jibreel (peace be upon him) took me to the second heaven and asked its gatekeeper to open the door, and here too, as before, questions and answers took place. Hazrat Anas (may Allah be pleased with him) says that Hazrat Ubayy (may Allah be pleased with him) informed that in the heavens, the Prophet (peace and blessings be upon him) met Hazrat Adam, Idris, Musa, Isa, and Ibrahim (peace be upon them), but he did not specify the heavens, only mentioning that he found Hazrat Adam (peace be upon him) in the lowest heaven and Hazrat Ibrahim (peace be upon him) in the sixth heaven. When Hazrat Jibreel (peace be upon him) took the Prophet (peace and blessings be upon him) past Hazrat Idris (peace be upon him), he said, "Welcome, O righteous Prophet and righteous brother." I asked, "Who is he?" Jibreel (peace be upon him) replied, "This is Hazrat Idris (peace be upon him)." Then I passed by Hazrat Musa (peace be upon him), and he said, "Welcome, O righteous Prophet and righteous brother." I asked, "Who is he?" Jibreel (peace be upon him) replied, "This is Hazrat Musa (peace be upon him)." Then I passed by Hazrat Isa (peace be upon him), and he said, "Welcome, O righteous Prophet and righteous brother." I asked, "Who is he?" Jibreel (peace be upon him) replied, "This is Hazrat Isa (peace be upon him)." Then I passed by Hazrat Ibrahim (peace be upon him), and he said, "Welcome, O righteous Prophet and righteous son." I asked, "Who is he?" Jibreel (peace be upon him) replied, "This is Hazrat Ibrahim (peace be upon him)." Then I was taken further up until I reached a place where I could hear the sound of pens moving. At that moment, Allah Almighty made fifty prayers obligatory upon my Ummah. I took this gift and returned, and passed by Hazrat Musa (peace be upon him). He asked, "What has your Lord made obligatory upon your Ummah?" I told him that fifty prayers had been made obligatory. Hazrat Musa (peace be upon him) said to me, "Return to your Lord; your Ummah will not have the strength to perform so many prayers." So I returned to my Lord and requested Him, and He reduced some of it (which eventually was reduced to five prayers). But Hazrat Musa (peace be upon him) again advised me to return. This time it was said, "The prayers are five, but the reward is fifty. My word does not change here." On my return, Hazrat Musa (peace be upon him) again advised me to seek further reduction, but I said to him, "Now I feel shy before my Lord." Then I was taken to Sidrat al-Muntaha, which was covered by such colors whose reality I do not know. Then I was admitted into Paradise, where I saw tents of pearls, and the soil there was musk.
