Bukhari

Hadith Commentary:
From this, no one should assume that it is prohibited for the pilgrim (haji) to perform a supererogatory circumambulation (nafl tawaf) after the arrival circumambulation (tawaf al-qudum); rather, the Messenger of Allah (sallallahu alayhi wa sallam) was engaged in other matters and was staying away from the Ka‘bah, that is, in Muhassab.
Therefore, until the completion of Hajj, the Prophet (sallallahu alayhi wa sallam) did not have the opportunity to come to the Ka‘bah and perform a supererogatory circumambulation (nafl tawaf).

Hadith Commentary:
(1)
Imam Bukhari rahimahullah means that if someone, after performing the arrival circumambulation (tawaf al-qudum), due to being occupied with other matters, does not visit the House of Allah (Bayt Allah) again before the standing at Arafat (wuquf ‘Arafat), nor performs any supererogatory circumambulation (nafl tawaf), then there is no restriction upon him.
This does not mean that performing a supererogatory circumambulation is prohibited, because the Prophet sallallahu alayhi wa sallam did not forbid performing tawaf during this period.
It is possible that the Messenger of Allah sallallahu alayhi wa sallam did not perform tawaf before the standing at Arafat so that people would not consider it obligatory, whereas declaring it obligatory would be a hardship.
The virtue of supererogatory circumambulation is agreed upon by all scholars; however, Imam Malik’s position is that it is not permissible for a pilgrim (haji) to perform a supererogatory circumambulation before the standing at Arafat until he completes his Hajj.
He has presented the aforementioned hadith as evidence for this, but this position is questionable because the Messenger of Allah sallallahu alayhi wa sallam, after performing the circumambulation of the House of Allah and the sa’i between Safa and Marwah, went to the valley of Muhassab, which is far from the Ka’bah. There, due to being occupied with other matters, he did not have the opportunity to come to the Ka’bah and perform tawaf until the completion of Hajj.

According to us, there is latitude in this matter; therefore, whoever wishes to perform tawaf after the arrival circumambulation may do so at any time, whether during the night or day. Especially for those coming from distant places, performing tawaf is better.
And Allah knows best.
