Hadith 1699 Amr bin Shu`aib on the authority of his grandfather
said: The Messenger of Allah
prohibited (us) from buying and selling in the Masjid; (he also prohibited us from) making announcement in it about something lost and from reciting poems in it. [Abu Dawud and At-Tirmidhi].
Commentary:1. Some `Ulama' have stated that the prohibition in the above stated Ahadith is in the nature of aversion and disgust if the acts mentioned in the Hadith do not lead to disturbing those engaged in worship (be it Salat, recitation of the Qur'an or similar good acts) in the Masjid. If they do disturb the worshippers, then the prohibition would be absolute.
2. Recitation of such poems is prohibited which relate to love stories and romantic tales. There is no harm in reciting such poems in Masjids which relate to the Oneness of Allah, obedience of His Prophet
, and other subjects meant for the reformation of Muslims.
3. It is permissible to talk about the problems of Muslims and any other issues which are concerned with the welfare of community at large.
4. It is prohibited to hold Qawwali (singing spiritual topics) in Masjids because it is accompanied by music and musical instruments. The verses recited in Qawwali are largely based on exaggeration and go beyond the limits prescribed by the Shari`ah. Such things unnecessarily pacify the sentiments of the public and incline them to inaction. It is a pity that many people regard Qawwali permissible, which is sheer ignorance.
