ETIQUETTE OF DUA:Should the hands be held together when raising them or should there be a gap between them?
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) stated in al-Sharh al-Mumti’ (4/25) that they should be held together. What he said is: “As for separating them and holding them far apart from one another, there is no basis for that in the Sunnah or in the words of the scholars.” End quote.
Raising the hands. Abu Dawood (1488) narrated that Salmaan (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Your Lord, may He be blessed and exalted, is Kind and Most Generous, and He is too kind to let His slave, if he raises his hands to Him, bring them back empty.” Classed as saheeh by Shaykh al-Albaani in Saheeh Abi Dawood, 1320.
The palm of the hand should be raised heavenwards, in the manner of a humble beggar who hopes to be given something. Abu Dawood (1486) narrated from Maalik ibn Yasaar (may Allaah be pleased with him) that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “When you ask of Allaah, ask of Him with the palms of your hands, not with the backs of them.” Classed as saheeh by Shaykh al-Albaani in Saheeh Abi Dawood, 1318.
