The Prophet said: "Sins are expiated by well-performed ablution despite difficulties, increasing the number of steps one takes towards the mosque, (and waiting for the next prayer after prayer)." (Using translation from Ibn Mājah 428)
"إسْباغُ الوضوء في المكاره، وإعمال الأقدام إلى المساجد، وانتظار الصَّلاة بعْدَ الصَّلاة يغْسِلُ الخطايا غسْلًا ".
