Is the ḥadīth that states: "Whoever prays twelve rakʿahs in a day and night, a house will be built for him in Paradise," meaning that whoever consistently performs them will have one house built for him in Paradise, or that houses will be built for him according to the number of days he prayed them?

The hadith on the virtues of supererogatory prayers is narrated with two wordings:

1. The first wording indicates that whoever prays the twelve regular rak'ahs in a single day will have a house built for him in Paradise. If he continues to observe them for many days, he will have houses equivalent to the number of days. A number of companions and imams adopted this apparent meaning, and Sheikh Ibn 'Uthaymin supported it.

2. The second wording indicates that daily perseverance in these regular prayers is a condition for a house to be built in Paradise. This wording is supported by the Prophet's (peace be upon him) saying, "every day" and "whoever perseveres." A number of imams adopted this apparent meaning, and Sheikh Ibn Baz inclined towards it.

The more probable view is that the promise is specific to those who regularly observe these supererogatory prayers, because an absolute statement is interpreted in light of a restricted one.
