What is the reward for one who leaves his home in a state of ritual purity?

Question:
What is the ruling on the one who leaves his home in a state of ritual purity, such that he has a good step, and a step that erases a sin, or something to that effect? What is your opinion of the one who leaves without being in a state of ritual purity and performs the ablution in the mosque?

Answer:
It is better to perform the ablution in his home, as stated in the hadith. If he leaves his home in a state of ritual purity, Allah records for him with every step: Allah raises him thereby a degree, removes from him thereby a sin, and records for him thereby a good deed, until he reaches the mosque. And he remains in prayer as long as he is waiting for the prayer.
