This article is devoted to a discussion of old age in terms of Muslim theology. It starts with a brief reminder of Muslim religious anthropology. In the next part I focus on what the verses of the Quran say about old age, and how these verses were interpreted by Muslim scholars. The Quran instructs primarily being a good and caring in relation to old parents, presenting, among others, the stories of the prophets who treated their parents in a very noble and merciful way. I also focus on numerious hadiths discussing various issues related to old age - calling for showing respect to every older man, regardless of his or her race, religion or social origin. In the final passages I draw attention to some elements of Islamic etiquette and Sharia referring to aging and the elderly.
