Rasulullah suka memulai dari sebelah kanan saat bersuci (wudhu)

Imam Bukhari : 163

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ قَالَ حَدَّثَنَا شُعْبَةُ قَالَ أَخْبَرَنِي أَشْعَثُ بْنُ سُلَيْمٍ قَالَ سَمِعْتُ أَبِي عَنْ مَسْرُوقٍ عَنْ عَائِشَةَ قَالَتْكَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُعْجِبُهُ التَّيَمُّنُ فِي تَنَعُّلِهِ وَتَرَجُّلِهِ وَطُهُورِهِ وَفِي شَأْنِهِ كُلِّهِ

It was narrated to us by [Hafsh bin 'Umar] who said: It was narrated to us by [Shubah] who said: It was narrated to me by [Asy'ath bin Sulaim] who said: I heard [my father] from [Masruq] from ['Aishah] who said: 'The Prophet, peace and blessings be upon him, liked to start with the right side when putting on sandals, combing his hair, purifying himself, and in all his affairs.'
