46. In Islam, can we see Allah if
we go to heaven?

Yes. According to a hadith, the Companions once asked the Prophet if we would see God in Paradise. The hadith is as follows:

During the lifetime of the Prophet some people asked, ‘O God’s Messenger! Shall we see our Lord on the Day of Resurrection?’ The Prophet said, ‘Yes. Do you have any difficulty in seeing the sun at midday when it is bright and there is no cloud in the sky?’ They replied, ‘No.’ He then said, ‘Do you have any difficulty in seeing the moon on a full moon night when it is bright and there is no cloud in the sky?” They again replied, ‘No.’ The Prophet said, ‘(Similarly), you will have no difficulty in seeing God on the Day of Resurrection, just as you have no difficulty in seeing either the sun or the moon.’ (Sahih al-Bukhari, hadith no. 4581)
