SHAFAQNA (Shia International News Association) – Some of the ways to thank God include Fasting, thanksgiving prayers (Salaats), thanksgiving prostration (Sijda) and other good deeds which will cause a believer to get closer to the Almighty. The most important point in thanksgiving is to appreciate the blessings from Allah (SWT) in a knowledgeable way. This type of appreciation needs knowledge, understanding and thought. Because when a devout believer recognises the God’s blessing and gains insight into that blessing then he/she will give thanks and appreciate that blessing. After reaching that level of understanding, giving thanks to Allah (SWT) for the blessings is to put into practice all the pillars of the religion and praying .
