What is the ruling on combining two prayers without fear or rain, based on the hadith of Ibn 'Abbas in that regard, as found in Sahih Muslim?

The questioner : May Allah forgive you, O Shaykh: It is reported in Sahih Muslim from Ibn 'Abbas: : Is this hadith restricted? And if someone were to say: I will act upon this hadith?

The Shaykh : We say: Yes, if you wish to act upon this hadith, who can stop you?
But Ibn 'Abbas (may Allah be pleased with him) said: , and his statement implies that there must be a cause, such as fear, rain, severe cold, or something similar. This is indicated by the fact that he said: meaning: so that it does not cause hardship. It is derived from this hadith that if any matter causes you hardship if you were to pray each prayer in its time, then it is permissible for you to combine. Therefore, it is permissible for the sick person for whom it is difficult to pray at every time to combine. The scholars of the Hanbali school even said: It is permissible for a nursing woman whose child frequently needs to nurse and who is harmed by it to combine the midday and afternoon prayers due to hardship, and to combine the sunset and night prayers due to hardship. The criterion is hardship; whenever hardship exists, combining is permissible.
