(Second chain) The Noble Prophet, peace and blessings be upon him, said: When the iqamah for prayer has been called, then there is no other prayer except the obligatory prayer.

Sayyiduna Abdullah bin Sarjis (may Allah be pleased with him) narrates: The morning prayer was established, and the Messenger of Allah (peace and blessings be upon him) saw a man who was performing the two Sunnah units of Fajr. After finishing the prayer, the Prophet (peace and blessings be upon him) asked him: Which prayer did you consider as the obligatory prayer, the one you performed alone or the one you performed with us?

Abdullah bin Malik (Ibn Buhaina) (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) passed by a man while the iqamah had been pronounced, and he was performing the two Sunnah rak'ahs of Fajr. The Prophet (peace and blessings be upon him) said something to him, but we could not understand it. When we finished the prayer, we surrounded that man and asked him: What did the Messenger of Allah (peace and blessings be upon him) say to you? He said: The Prophet (peace and blessings be upon him) said to me: It is near that one of you begins to perform four rak'ahs for the Fajr prayer.

(Second chain) The Noble Prophet (peace and blessings be upon him) passed by this man, and he was performing a lengthy prayer before the Fajr prayer. The Prophet (peace and blessings be upon him) said to him: Do not make this prayer like the Zuhr prayer; rather, keep a separation between these two.

It is narrated from Malik bin Buhaina that a man entered the mosque after the iqamah had been called, but he began to offer the two Sunnah rak'ahs of Fajr. When the Messenger of Allah (peace and blessings be upon him) finished the prayer, the people surrounded that man, and the Prophet (peace and blessings be upon him) said to him: Have you performed four rak'ahs of the Fajr prayer?

Sayyiduna Abdullah bin Malik (Ibn Buhaina) رضي الله عنه narrates that the Noble Prophet صلى الله عليه وآله وسلم came for the morning prayer and Sayyiduna Ibn Qishb was praying. The Prophet صلى الله عليه وآله وسلم struck his shoulder with his hand and said: O Ibn Qishb! Are you praying the morning prayer as four rak‘ahs or twice? This doubt occurred to Ibn Jurayj.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) says: The iqamah for the Fajr prayer was given, a man stood up and began to offer two sunnah rak'ahs. The Messenger of Allah (peace and blessings be upon him) pulled him by his garment and said: Are you performing four rak'ahs for the Fajr prayer?

Sayyiduna Yazid bin Aswad says: We performed the Farewell Hajj with the Messenger of Allah, peace and blessings be upon him. He led us in the Fajr prayer, and when he turned towards the people and sat down, he saw that there were two men sitting at the back of the people; they had not prayed with the people. The Messenger of Allah, peace and blessings be upon him, said: Bring these two to me. The two men were brought, and the flesh of their shoulders was trembling. The Messenger of Allah, peace and blessings be upon him, asked them: What prevented you from praying with the people? They said: O Messenger of Allah! We had already prayed at our homes. The Messenger of Allah, peace and blessings be upon him, said: Do not do so in the future, and when any of you has prayed at home and then finds the congregational prayer with the Imam, he should also pray with him; it will become a voluntary prayer for him. One of the two said: O Messenger of Allah! Please seek forgiveness from Allah for me. So the Messenger of Allah, peace and blessings be upon him, sought forgiveness for him. Then the people rose towards the Messenger of Allah, peace and blessings be upon him, and I also rose with them. At that time, I was the best and strongest young man among the people, so I made my way through the people until I reached the Messenger of Allah, peace and blessings be upon him. Then I took his hand and placed it on my face or chest. I did not find anything better and cooler than the hand of the Messenger of Allah, peace and blessings be upon him. On that day, he was in the Mosque of Khaif (in Mina).

Sayyiduna Mihjan (may Allah be pleased with him) says: I came to the Noble Prophet (peace and blessings be upon him), and in the meantime, the iqamah for prayer was called, but I remained seated (and did not pray). The Prophet (peace and blessings be upon him) said to me: Are you not a Muslim? I replied: Why not! The Prophet (peace and blessings be upon him) said: What kept you from praying with the people? I said: O Messenger of Allah, I had already performed the prayer at home. The Prophet (peace and blessings be upon him) said: (Still) perform the prayer with the people. And in another narration: When you come, perform the prayer with the people, even if you have already performed the prayer at home.

(Second Chain) Sayyiduna Mihjan (may Allah be pleased with him) narrates that he was in the gathering of the Messenger of Allah (peace and blessings be upon him), when the call to prayer was given. The Messenger of Allah (peace and blessings be upon him) stood up and led the prayer. When he (peace and blessings be upon him) returned, he saw that Mihjan was still sitting in the same place, so he (peace and blessings be upon him) asked him: What prevented you from praying with the people? Are you not a Muslim? ... ... . (As in the previous hadith)
