Q: Is it permissible to offer more than two Rak`ahs (units of Prayer) after making Wudu' (ablution) as has been reported in the Hadith narrated by
(may Allah be pleased with him) that the Messenger of Allah said to
O Bilal, "Tell me of your best promising deed - you think - in Islam, for I heard your footsteps in front of me in Paradise." Bilal replied, "I did not do anything worthy of mention except that whenever I performed Wudu' during day or night, I prayed after that Wudu' as much as I could.
Authenticity of this Hadith is agreed upon by both Al-Bukhari and Muslim.
the regular Sunnah is to perform two Rak`ahs after Wudu' based on the Hadith mentioned above and similar Hadith. However, it is permissible for a person to offer as many additional supererogatory prayers as he can, provided that they are offered in times when prayer is not forbidden.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
