The Limits of Ablution, Its Order and Reward
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 11
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «وَ إِنْ نَسِيتَ حَتَّى تَقُومَ مِنَ اَلصَّلاَةِ فَلاَ آمُرُكَ أَنْ تُعِيدَ».
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "And if you forget (to rotate your ring in ablution) until you stand in Salat, then I do not command you to repeat it (Salat)."
