Many of us have showers everyday, or even every morning and evening, and if you hear that someone hasn't taken a shower one day, you think that he is "unclean" and "dirty", and sometimes you can smell the person.
But have we taken a spiritual morning or evening shower today? Do we take a spiritual shower everyday? To purify the stench/smell of our souls? This shower is the shower of the Qur'an, the shower of the dhikr of Allah (Hallowed is He) and thus the shower of the Mercy of Allah Most High which removes our sins.
The Prophet said "No people gather together in one of the houses of Allah, reciting the Book of Allah and studying it among themselves, but tranquillity and peace descends upon them, mercy envelopes them, the angels surround them, and Allah makes mention of them amongst those who are with Him. And whosoever is slowed down by his actions will not be hastened forward by his lineage" (Muslim)
The Prophet (Sallallahu alaihi wa sallam) said “The Quran is an intercessor, and it is rightfully believed in. Whoever puts it in front of him, it will lead him to Paradise; whoever puts it behind him, it will steer him to the Hellfire.” [At-Tabarani]
