Here is a benefit taken from the noble Sheikh Abdullah Al-Iryani hafidahu’Allah in his explanation of the Prophet’s Prayer Described:
((Occasionally raising the hands between the two sujuuds))
On the authority of Wa’il Ibn Hujr with an authentic chain of narration the Prophet (peace be upon him) at times would raise his hands when he rose from the sujuud. It has been authentically established that Anas Ibn Malik and Abdullahi Ibn Umar raised their hands between the two sujuuds as it is found in the Musnaf of Ibn Abee Shaybah (Volume 1, Page 271). We say this act was done occasionally to reconcile with the hadith of Abdullahi Ibn Umar collected in Sahih Bukhari * that the Prophet (peace be upon him ) NEVER raised his hands when raising from sujuud.
The Sheikh is referring to the following hadith:
Al-Bukhaari (735) and Muslim (390) narrated from Ibn ‘Umar that the Messenger of Allah (blessings and peace of Allah be upon him) raised his hands until they were level with his shoulders when he began to pray, when he said takbeer before bowing (rukoo‘), and when he lifted his head from bowing, he raised his hands in the same manner and said “Sami‘a Allahu liman hamidah Rabbana wa laka’l-hamd (Allah hears those who praise Him; Our Lord to You be praise).” But he DID NOT do that when he prostrated (sujood).
The Sheikh hafidahu’Allah continues on to say, “A group of scholars went with the opinion that raising the hands between the two sujuuds is a recommended act”.
