Voluntary prayer between the two prayers at Muzdalifah

It is narrated from Abu Mijlaz that he was with Sayyiduna Ibn Umar (may Allah be pleased with them both). He came to Jam' (Muzdalifah) and prayed Maghrib, then turned to us and said: Now it is the time of the second prayer (the prayers are joined). And he did not pray anything voluntary between the two.

Abd al-Rahman bin Yazid said: I performed Hajj with Sayyiduna Abdullah (may Allah be pleased with him). When he came to Jam' (Muzdalifah), the adhan was given and the iqamah was said, then he led three rak'ahs of Maghrib, then he ate his evening meal, then the adhan was given and the iqamah was said, and he prayed two rak'ahs of Isha.

Sayyiduna Umar (may Allah be pleased with him) also did as Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) did.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) combined the two prayers at Jam' (Muzdalifah) and did not pray anything voluntary between them.
