We have been sent in this world to worship Allāh Ta’ala. If in our negligence, we have missed acts of worship in the past which we owe to Allah Ta’ala and rights we owe to His servants, it is necessary for us to fulfil them before leaving this world. This book has been prepared to facilitate in fulfilling these great duties and eventually make our bond with Allāh Ta’ala strong. This book includes charts to keep track of missed Salahs, Fasts, Zakah, Sadaqah al-Fitr, etc.
