The Prophet (may Allah's peace and blessings be upon him) encourages raising the hands during supplication and informed that Allah Almighty is (Bashful), possessing great bashfulness, and does not withhold giving. He does for the slave what brings him joy and refrains from what harms him. (Munificent) as He gives without being asked, so how much more after being asked! He feels bashful of His believing slave to return his hands empty of His answer and disappointed after they have been raised in supplication.

Explanation in Arabic
يَحُثُّ النبيُّ صلى الله عليه وسلم على رفع اليدين أثناء الدعاء، وأخبر أنَّ الله سبحانه (حَيي) كثير الحياء، ولا يترك العطاء، يفعل بالعبد ما يَسُرُّه، ويترك ما يَضرُّه، (كريم) يعطي من غير سؤال فكيف بعد السؤال! يَستحيي مِن عبده المؤمن أنْ يَرُدَّ يديه بعد رفعِها للدعاء فارغتين خاليتين خائبتين من إجابته.
كلما أظهر الإنسان الافتقار إلى الله تعالى والتعبد، كان أرجى له وأقرب للإجابة.
الترغيب في الدعاء، واستحباب رفع اليدين فيه، وأنه من أسباب الاستجابة.
