Beginning with the Right

That is washing the right hand before the left – and likewise the feet.

‘Aaishah (radhiAllaahu ‘annaa) said:

Rasoolullah (sallallaahu ‘alaihi wa sallam) used to like to begin with the right in putting on shoes, combing his hair, in purification and in all of his affairs.

[Al-Bukhaaree (al Fath) 1/235, Muslim (no.267) and others]

Abu Hurairah (radhiAllaahu’anhu) narrates that the Prophet (sallallaahu ‘alaihi wa sallam) said

When you dress and when you make wudoo , then begin with the right.

[Abu Dawood (4141), at-Tirmidhee (1766), an-Nasaa’ee (402). 
Al-Albaanee declares it to be saheeh].
