Orphans and widows constitute a significant portion of any developing or underdeveloped society. However, their basic needs are not properly catered for there by subjecting them to various forms of hardships. This is due to the negligence on the part of both individuals and the state as a whole towards the wellbeing of the orphans and widows. As such Waqf is seen as a vehicle through which the welfare of orphans and widows can be improved. Data for the study were collected through administration of questionnaire and interview. 120 questionnaires were administered to respondents (orphans and widows’ beneficiaries) and data collected for 105 respondents were analysed using percentages frequency distribution and binary logistic regression tools of analysis. Binary logistic regression has shown that both access to clothing, skill acquisition, education support provide by Salam Waqf significantly improves the welfare of orphans and widows. However, accesses to health care support do not have significant impact to the beneficiaries. Lack of awareness and inadequate financial support hinders the effective functioning of Waqf. The study therefore, recommends among others, investing more in Waqf foundation especially by targeting orphans and widows, increased awareness on Waqf, liaising with local, state and federal government in order to improve Waqf as well as providing laws and regulatory body that will be supervising and protect the activities of Waqf foundation in order to achieve sustainability.
