Nawawi on making up missed prayers: scholarly consensus
In the Name of Allah, Most Merciful and Compassionate
Imam Nawawi stated in his al-Majmu` Sharh al-Muhadhdhab (3.86):
“There is consensus (ijma`) of the scholars whose opinion counts that whoever leaves a prayer intentionally must make it up. Abu Muhammad Ali Ibn Hazm differed with them on this, saying that such an individual cannot ever make them up and it is not at all valid to make them up. Rather, he said, one must do much good works and voluntary prayer in order that one’s scales be heavied on the day of judgement and one must seek Allah’s forgiveness and repent. This position of his, along with being in opposition to scholarly consensus (ijma`), is invalid in terms of the proof
Among the proofs for the obligation to makeup is that if makeup prayers are obligatory for the one who left the prayer forgetfully, then doing so for the one who left the prayer deliberately is more obviously incumbent.”
Imam Nawawi is referring here to the hadith related by Anas that the Messenger of Allah (Allah bless him and give him peace) said,
“Whoever forgets a prayer must perform it when they remember it ” [Bukhari (597), and Muslim (684)]
After Imam Nawawi’s time, the aberrant position of Ibn Hazm was embraced by Ibn Taymiyya and his loyal student, Ibn Qayyim, and soundly rejected by the scholars in their time and after.
In our times, this aberrant ( shadhdh) opinion has been adopted by some modernists, but it remains invalid to follow.
