Is it permissible for me, when I am lazy, to perform tayammum instead of wudu' for sleep?

The questioner: That is, is it permissible to perform tayammum, meaning instead of going to the bathroom and performing wudu', is it permissible to perform tayammum for sleep and is that considered ritual purity?

The Shaykh: If he is, meaning, not energetic.

The questioner: Yes.

The Shaykh: And the matter is between sleeping while in a state of major ritual impurity, or sleeping while having performed tayammum, which is a state of less than complete purity. The latter is better than the former. But without a doubt, the best option is complete purity. Therefore, we mentioned in my book "Adab al-Zafaf" (Etiquette of the Wedding) that for a Muslim in a state of major ritual impurity, there are conditions, the best of which is to purify himself and then sleep. Then, if he does not want to perform the full ritual bath, he should perform wudu' and then sleep. And if, as came in the question just now, he is lazy and has no energy to get up and perform wudu', especially if it is a cold, winter night, then at that time he performs tayammum. These are ranks. But it is permissible for him to sleep while in a state of major ritual impurity as he is, so it is not forbidden for him. But this is from the category of a dispensation, not from the category of dire necessity. And the virtue lies in the previous ranks.
