Question: What is the ruling of [performing] the tahiyyatul-masjid (two rak'ah Sunnah prayer upon entering the masjid and before sitting down) just after the adhaan of [the] maghrib [prayer] and before the [Maghrib] prayer [itself, considering] whilst the time period between the adhaan and the iqaamah is short; And also what is the ruling of [performing] the voluntary prayer before the Maghrib prayer?
Response: The tahiyyatul-masjid [prayer] is a recommended Sunnah [to be done] at all times, even during the prohibited times (between after the fajr prayer and sunrise and between after the 'asr prayer until Maghrib) according to the correct of the two opinions of the scholars, based upon the saying of the Prophet ﷺ:
As for the prayer after the Maghrib [prayer] adhaan, and before the iqaamah, [then] it is a Sunnah based upon the saying of the Prophet ﷺ:
and thirdly he said:
And the companions of the Prophet ﷺ would hasten to perform the two rak'ah [Sunnah] prayer before the iqaamah of [the] Maghrib [prayer] and the Prophet ﷺ would see them [doing so] and did not prohibit them from that [transmitted by al-Bukhaaree no.625 and Muslim no.836], rather he encouraged them in that as mentioned in the earlier hadeeth.
