It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him), the Messenger of Allah (peace and blessings be upon him) said: There are two prayers after which no further prayer is to be performed: one is the Fajr prayer, until the sun rises, and the other is the Asr prayer, until the sun sets.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) has narrated a similar hadith of the Prophet.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: There is no prayer after the Asr prayer until the sun sets, and there is no prayer after the Fajr prayer until the sun rises high or the time of Duha comes.

Nasr bin Abdur Rahman narrates that he performed Tawaf of the Ka'bah after Asr or Fajr with his grandfather, Sayyiduna Mu'adh bin Afra' Qurashi (may Allah be pleased with him), but his grandfather did not offer the prayer of Tawaf. When Nasr asked him about this, he replied: The Messenger of Allah (peace and blessings be upon him) said: There is no prayer after two prayers: after the Fajr prayer until the sun rises, and after the Asr prayer until the sun sets.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him), he says: The beloved people bore witness to me, and the most beloved among them to me is Sayyiduna Umar bin Khattab (may Allah be pleased with him), they bore witness that the Prophet of Allah (peace and blessings be upon him) said: There is no prayer after Asr until sunset, and after Fajr until sunrise.
