2.6 KNOCKING AND RINGING
Knock at the door, or ring the door’s bell in a pleasant way and not louder than is necessary to make your presence known. Do not knock loudly and violently or ring the bell continuously. Remember that you are a visitor and not a thug or an oppressor who is raiding the house and frightening its occupants. A woman came to Imam Ahmad bin Hanbal seeking his opinion on a religious matter. She banged at his door loudly. He came out saying, ‘This is the banging of policemen.’ Al-Bukhari reported in Al-Adab Al-Mufrad that the companions of the Prophet (صلى الله عليه وسلم) used to knock on the door of the Prophet with the tips of their nails.
This nimble and gentle knocking, or ringing, is appropriate for those whose living quarters are close to the door. For those living farther from the door, it is appropriate to knock on their door, or ring the bell loud enough to enable them to hear it, without banging. In this regard the Prophet (صلى الله عليه وسلم) said, ‘Gentleness adorns every act, its absence will tarnish it.’ In addition, Muslim reported that the Prophet also said, ‘Whoever lacks kindness, lacks all good things.’
Leave an adequate time between two knocks, or rings. This will enable those performing ablution, praying, or eating, to finish without rushing. Some scholars estimate this interval to be that of the praying time of four rak’as. Keep in mind that a person may have just started the prayers just before you rang the door bell.
After three spaced knocks, or intermittent rings, you may feel that the person you came to see is busy, otherwise, he or she would have answered you. If this is the case, leave. Al-Bukhari and Muslim reported that the Prophet (صلى الله عليه وسلم) said: ‘If you asked permission three times, and were not granted permission, then you must leave.’
