Hanging a calendar issued from a bank in a Masjid

A: It is not permissible to hang calendars and Ramadan fasting calendars that are issued by some banks or commercial institutions in Masjids, for it results in some violations of Shari`ah (Islamic law), such as promoting forbidden transactions and making the Houses of Allah an object for advertising for commercial products. This violates the sanctity of Masjids and the purpose for which they are built, meaning offering Salah (Prayer), reciting the Qur'an, teaching people goodness, urging them to do it, and warning them against evil. All this comes under the Saying of Allah (Exalted be He): Help you one another in Al-Birr and At-Taqwâ (virtue, righteousness and piety); but do not help one another in sin and transgression. And fear Allâh. Verily, Allâh is Severe in punishment. (Part No. 5; Page No. 240) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
