Abu Dawud

1870. English Commentary: In the chain of this hadith is Muhajir bin Ikrimah al-Makki, who is majhool (unknown). And among the narrations reported on this issue, there is none that is strong enough to establish that raising the hands upon seeing the House of Allah (Baytullah) is legislated. Only some reports and traditions have been narrated regarding making supplication (du'a) in this context. (Nayl al-Awtar 5/42) A narration is often cited: "The hands are not to be raised except in seven places..." and among them is upon seeing the House of Allah. This narration is extremely weak and not admissible as evidence. (Nasb al-Rayah, Kitab al-Salah, 389/38) ➊ Hadith 38]

This narration is weak. The Jews did not raise their hands upon seeing the Ka'bah (Baytullah) because they did not even go to the Ka'bah; rather, they were enemies of the Ka'bah. It is possible that the meaning is that the Jews raise their hands when seeing their own places of worship or Bayt al-Maqdis, and we should not follow their way; or it could mean that it is the Jews who raise their hands at inappropriate times and places, and we should not do so. Another interpretation that has been mentioned is that the Jews would raise their hands upon seeing the Ka'bah out of contempt, and by this, they intended to express their desire to destroy it. The first meaning appears to be the most likely. In any case, the aforementioned narration is weak. On the contrary, there is an established report from Ibn Abbas (radi Allahu anhu) in a mawquf form, so if someone raises both hands out of reverence when seeing the Ka'bah, there is no harm in it. And Allah knows best. For details, see: (Manasik al-Hajj wal-‘Umrah by al-Albani: p. 20)

English Commentary:
1:
Here, the interrogative is for the purpose of negation. In the narration of Abu Dawud, instead of ((أًفَكُنَّا نفعلُه)), it is ((فلَم يكُنْ يَفْعَله)), and in the narration of Nasa’i, it is ((فلَم نَكُنْ نَفْعَله)), but this narration is weak, so it is not correct to use it as evidence. On the contrary, from authentic ahadith and athar, it is established that raising the hands upon seeing the House of Allah (Baytullah) is proven.

Note:
(In the chain of narration is Muhajir ibn ‘Ikrimah, who is a narrator of weak hadith, and there is also a difference in the text itself regarding affirmation and negation.)
