ANSWER:

We understand the Quran through the sunnah! The Quran can’t contradict itself nor can the sunnah. The Prophet salla Allahu Alaihi wa Sallam used to kiss his wives and go to prayer without performing wudhu! 

In ayah 5:6 In Qirat of Hafs it is known that the word “laamasa” with an alif on laam means touching with desire or intercourse which invalidates wudu. But in the Qira’ah of Hamza and Kisa’i it is recited as أولمستم without alif and this ayah gives preference to Imam Shafi’s ruling about the breaking of Wudhu but other Fuqahas example Imam Maliki and Ahmed bin Hanbal gave a different ruling. Why?
