Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah ﷺ said, "Should I not direct you to something by which Allah obliterates the sins and elevates (your) ranks." They said: "Yes, O Messenger of Allah". He said, "Performing Wudu' properly, even in difficulty, frequently going to the mosque, and waiting eagerly for the next Salat (prayer) after a Salat is over; indeed, that is Ar- Ribat".

[Muslim].

الخامس عشر: عنه قال رسول الله ﷺ: " ألا أدلكم على ما يمحو الله به الخطايا، ويرفع به الدرجات؟" قالوا: بلى يا رسول الله، قال: " إسباغ الوضوء على المكاره، وكثرة الخطا إلى المساجد، وانتظار الصلاة بعد الصلاة، فذلكم الرباط" ((رواه مسلم)).
