We should always consider Allah’s pleasure in all our affairs of life it’s not only restricted that when we are doing our rituals or prayers we have to focus on it. Therefore if we remember Allah (swt) and seek his acceptance then inshallah we will see the quality of our actions. In Islam meditation means sincerity and devotion in our actions so if we achieve it our actions will be valuable otherwise if we are sitting whole night in meditation mode without sincerity ( Ikhlas) then it’s waste of time.
