THE MARVEL OF POSITIVE THINKING IN ISLAM – I

In the name of Allah, the Gracious, the Merciful Our thoughts have a powerful ability to determine our feelings and emotional states and ultimately affect how we behave, for better or worse. Islam teaches us to direct the act reflection ( tafakkur ), or deep thought, towards the signs of Allah, the names and attributes of Allah, to his blessings and wonders, to hope in the Hereafter, and to optimism. By controlling our thought processes in a positive manner, we can increase the effectiveness of our prayers and worship as well as relieve ourselves from the anger, depression, and anxieties that worldly thoughts induce.
Contrary to popular belief, we have control over which thoughts we choose to follow. We may not have a choice over which particular thought occurs initially in our minds at a given time, but we do have a choice to either ignore it or pursue it.
Our voluntary thoughts are nothing more than inward statements. Hence, the rule is that we should only engage good thoughts or keep our minds silent.
Abu Huraira, RadhiAllahu Anhu, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, said: وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَسْكُتْ Whoever believes in Allah and the Last Day, let him speak goodness or remain silent.
