What is the authenticity of the chain of transmission for the two narrations: "Narrated to us Abu Bakr, who said: Narrated to us Wakee', who said: Narrated to us Fudayl ibn Ghazwan, from Nafi', from Ibn 'Umar, that he used to keep vigil between Dhuhr and 'Asr" and "Narrated to us Wakee', who said: Narrated to us Sufyan, from Ibrahim ibn Muhajir, from Ibrahim, who said: They used to liken the 'Isha prayer and what is between Dhuhr and 'Asr to the night prayer"? And what is the meaning of Ibn 'Umar keeping vigil between Dhuhr and 'Asr, and did he pray without interruption, and is it permissible to emulate him in that? And what is the meaning of likening the 'Isha prayer and what is between Dhuhr and 'Asr to the night prayer?

These two narrations were reported by Ibn Abi Shaybah and others, and no one has addressed their authenticity or weakness. It seems that Ibn Umar’s statement, "He revives what is between Dhuhr and Asr," means he performs voluntary prayers during that time, just as it was reported from Anas that he used to revive what was between Maghrib and Isha and would say, "This is the rising of the night." Reviving includes occupying the time with acts of obedience such as remembrance and prayer. As for continuous prayer without interruption, we have no knowledge of it, and there is no impediment to doing so, due to the desirability of performing many supererogatory prayers. As for the meaning of the narration, "They resemble the Isha prayer...", it seems that they are likening voluntary prayers between Maghrib and Isha and between Dhuhr and Asr to the night prayer in terms of superiority, because people are often heedless during these two times.
