About fragrant flowers (rayhan).
Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: Whoever is offered fragrant grass or a fragrant flower should not refuse it (i.e., should not decline to take it), because it carries no burden and its fragrance is pleasant.
