Q 1: When a person leaves the Masjid (mosque) to perform Wudu' (ablution) during the Khutbah (sermon) of Jumu`ah (Friday) and comes back, should he perform the supererogatory Salah (prayer) again? A: Whoever leaves the Masjid to perform Wudu' because he invalidated his Wudu' then comes back, it is a Sunnah for him to offer two Rak`ahs before he sits as Tahiyyat-ul-Masjid (two-unit Prayer to salute the mosque) because he is included in the general saying of the Prophet (peace be upon him): If anyone of you enters a Mosque, he should not sit until he has offered a two-Rak`ahs prayer. When he intends to offer the supererogatory Rak`ahs of Wudu' as well as Tahiyyat-ul-Masjid, it will be sufficient because it is a Sunnah for those who perform Wudu' to offer two Rak`ahs as supererogatory Salah for it. Abu Hurayrah (may Allah be pleased with him) narrated that the Prophet (peace be upon him) said to Bilal at Fajr (Dawn) Prayer: O Bilal, Tell me of the best deed you did after embracing Islam, for I heard your footsteps in front of me in Paradise.

(Part No. 6; Page No. 140) Bilal replied: I did not do anything worth mentioning except that whenever I performed Wudu' during the day or night, I prayed after that ablution as much as was written for me. Abu `Abdullah said: (Duff Na`layk i.e. the sound of your footsteps). Related by Al-Bukhari in his Sahih, vol. 2, p.48. It is permissible for one to perform any supererogatory Salah other than the times which are prohibited. The Prophet said: The (optional) Salah by night and day should consist of pairs of Rak`ahs.
