Answered by Shaykh Abu Usamah
Are there any conditions attached to Salatul Wudu?. I have been taught after a person makes wudu it is encouraged to make salatul wudu immediately afterwards before other Ibadah. Lets say one forgets to make salatul wudu afterwards and carries on with his/her Ibadah, can one make salatul wudu afterwards for the baraka? For example, lets say one makes wudu then makes Salatul Duhaa, Tahajud etc, could one then make Salatul Wudu afterwards if one forgot? Again if one makes the sunnah rakats before Thur could one make Salatul Wudu before the Fard salah if one forgot?
The Salah of Wudu and Tahiyyah al-Masjid will be fulfilled by offering any other salah after wudu’ or after entering the masjid. Hence if a person makes wudu’ and thereafter offers any salah (Fard or Nafl) that salah will take the place of Salah of Wudu’ also. The same applies to Tahiyyah al-Masjid. This is what Allamah ibn Abidin has mentioned in his Hashiyahon Al-Durr al-Mukhtarv2 p19 and v2 p24 Dar al-Fikr 1995.
