Praise be to Allaah.
We put this question to Shaykh Muhammad Saalih ibn ‘Uthaymeen, who replied as follows:
“If the Muslim students agree on something, this is OK, but if each Muslim group is adopting its own symbol, it is not right. The symbol or color that we recommend is bright green.”
Is there any daleel (evidence) for this color?
“No, but people like this color and in the Qur’aan it says (interpretation of the meanings): ‘Their garments will be of fine green silk’ [al-Insaan 76:21] and ‘Reclining on green cushions’ [al-Rahmaan 55:76].”
Is there any indication from the reports that the Prophet SAWS (peace and blessings of Allaah be upon him) had white and black banners that these colors are mustahabb in such cases?
“No, we cannot use these colors, because these were the banners in that time, and each era has things that are appropriate for it. But black now is one of the symbols of the Raafidah, as is well known.”
The crescent is commonly used as a symbol by Muslims to distinguish themselves from Christian groups who use the cross as a symbol. Is it permissible for us to use the crescent as a symbol in our publications and on our banners, to distinguish ourselves from other, non-Muslim groups?
“I do not think this is right, because the crescent was originally a symbol that was placed on graves that were worshipped instead of Allah. We read this in an answer given by some scholars and leaders of Daw’ah. But we could use a picture of the Ka’bah as a symbol, because it is the Qiblah of all Muslims.”
In some countries they put a crescent on Muslim places of worship to distinguish them from Christian places of worship, which have crosses on top of them. They do this so that people can tell them apart from a distance, because the architecture is often similar. Can we say that putting a crescent on the mosques or minarets of the Muslims is bid’ah?
“It is as you say (i.e., we can say that). It is sufficient for a mosque not to have a Christian symbol on it. Symbols may be something that is present, or something that is not present. If the Christians have a symbol, namely the cross, then the fact that the Muslims have no symbol is in itself a symbol. (i.e., we do not need to put anything).
And Allâh knows best.
