«من توضأ مثل وضوئي هذا ثم قام فصلى ركعتين لا يحدث فيهما نفسه بشيء غفر له ما تقدم من ذنبه»
The Prophet (peace and blessings be upon him) said:
"Whoever performs ablution like this ablution of mine, then stands and prays two rak'ahs in which his mind does not wander to anything else, his past sins are forgiven."
