Abu Umamah (RA) narrates: Rasulullah (SAW) said: Whoever stands up to perform his Wudhu, intending to offer Salah, then cleans his hands; the sins of his two hands fallout with the first drop of water. Then, when he rinses his mouth, and draws water into his nose and expels it; the sins of his tongue and two lips fallout with the first drop of water. Then, as he cleans his face, the sins of his hearing and seeing fallout with the first drop (of water). Then, when he cleans his two arms past the elbows, and his two feet past the ankles; he becomes free of all his offences and sins, just as was his state, the day his mother gave him birth. He (then) said: Then, when he stands for Salah; Allah elevates his position, and if he (merely) sits (without standing for Salah) even then his sitting is free of sins! Source: Musnad Ahmad.
We take bath regularly to clean our body of dirts, but how many of us offer regular prayers daily to clean the real dirts (sins)?
