The Limits of Ablution, Its Order and Reward
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 11
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «مَنْ تَوَضَّأَ وَ تَمَنْدَلَ كَتَبَ اَللَّهُ لَهُ حَسَنَةً وَ مَنْ تَوَضَّأَ وَ لَمْ يَتَمَنْدَلْ حَتَّى يَجِفَّ وَضُوؤُهُ كَتَبَ اَللَّهُ لَهُ ثَلاَثُونَ حَسَنَةً.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: 'Whoever performs ablution and wipes himself (with a towel) will have a good deed written for him. And whoever performs ablution and does not wipe himself until his ablution dries, Allah سبحانه وتعالى will write for him thirty good deeds.'.
