Being considerate of someone sleeping by not disturbing them is actually a charitable deed. The Messenger pbuh used to walk in and greet those awake in such a voice that they could hear, but those asleep were not disturbed at all.
Today our televisions, radios, CD players and other sound systems literally “blast” through the whole neighbourhood let alone disturbing poor family members or room mate…s! Do we phone at awkward times, knock the door so loudly, ring the bell like maniacs, speak so loudly on our phones whilst others are asleep or trying to sleep?
Let us become more conscious of those who are asleep and be considerate towards them whether in the house or elsewhere. Not only will we be earning a reward but we will prevent many a crisis from erupting and ease what may be unknown silent suffering.
