Answer: I say, and with God's success: From 'Uqbah ibn 'Amir (may Allah be pleased with him) who said: "We were responsible for tending the camels, and when it was my turn, I took them out in the evening, and I caught the Messenger of Allah (peace be upon him) standing and talking to the people, and I heard him say: 'There is no Muslim who performs ablution and does it well, then stands to pray two rak'ahs, focusing his heart and face towards them, except that Paradise becomes obligatory for him.' I said: 'How excellent this is,' reported in Sahih Muslim 1: 209. This is one of the etiquettes of ablution; see: Tabyin al-Haqaiq 1: 6-7, Majma' al-Anhar 1: 16, and Bada'i' al-Sana'i' 1: 23-24, and Allah knows best.
