The Ruling on Voluntary Prayers When Combining Prayers

Question:
I said: O honorable Shaykh, may Allah reward you, if a person does not perform voluntary prayers, what is the ruling for one who combines the midday and afternoon prayers, or the sunset and night prayers? Does he perform voluntary prayers or not?

Answer:
Yes, combining prayers does not prevent voluntary prayers; combining prayers does not prevent voluntary prayers. What prevents voluntary prayers is the intention. Because the Prophet (peace and blessings be upon him), when he shortened the prayer in the mosque, it was not reported that he performed the regular voluntary prayers (rawatib).
And Ibn 'Umar (may Allah be pleased with him) said: If I were not in a state of ritual impurity, I would have completed the prayer. So the one who breaks his fast does not perform the regular voluntary prayers (rawatib). As for voluntary prayers other than the regular ones, there is no prohibition; he prays the Duha prayer, prays at night, and performs the Witr prayer and the two rak'ahs of Fajr. He does not leave these, neither in residence nor in travel. The Witr and the two rak'ahs of Fajr—meaning the two rak'ahs of Fajr with the Witr—are not left, neither in travel nor in residence. What is prohibited are the regular voluntary prayers (rawatib) that accompany the Zuhr prayer, those that accompany the 'Asr prayer, and those that accompany the 'Isha' prayer; he does not perform these if he is experiencing distracting thoughts. He remembers Allah after the last prayer, performing the dhikr after the last prayer. Yes.
