Abu Dharr (may Allah be pleased with him) reported that the Prophet ﷺ said: “Charity is required from every part of your body daily. Ordering the good is charity. Eradicating the evil is charity. And what suffices for that (as a charity) are the two rak`ahs of Duha.
If the people knew what is the reward of making the call (for the prayer) and (of being in) the first row (in the prayer), and they found no other way to get this privilege except by casting lots, they would certainly cast lots for it. If they knew the reward of coming early, they would race for it, and if they knew the reward of the Ishâ` and morning (i.e. Fajr) prayers, they would go for the prayer even if they had to crawl to reach there. [Reported by Al-Bukhari]
The basic meaning of khushu` is the softness of the heart, its being gentle, still, submissive, broken, and yearning. When the heart is humble, so too is the hearing, seeing, head, and face; indeed all the limbs and their actions are humbled, even speech.
An article to clearly explain and comprehend the rewards of Istikharah: The Prayer of Guidance - We are humans, powerless in this sphere of life, knowledgeable only enough
to survive. So why shouldn't we turn to Allah and seek His perfect help
whenever we require it? Allah responds to the call of His servant when he
asks for guidance, and we are after all seeking to do something in order to
please Him.
