Muhammad orders people burned up in their houses, for not coming to prayer

In Sahih al-Bukhari, the most canonical hadith collection:
Volume 1, Book 11, Number 626:
Narrated Abu Huraira:

The Prophet said, "No prayer is harder for the hypocrites than the Fajr [pre-dawn] and the 'Isha' [evening] prayers and if they knew the reward for these prayers at their respective times, they would certainly present themselves (in the mosques) even if they had to crawl." The Prophet added, "Certainly I decided to order the Mu'adh-dhin (call-maker) to pronounce Iqama [second call to prayer] and order a man to lead the prayer and then take a fire flame to burn all those who had not left their houses so far for the prayer along with their houses."
Volume 1, Book 11, Number 617:
Narrated Abu Huraira:

Allah’s Apostle said,“By Him in Whose Hand my soul is I was about to order for collecting fire-wood (fuel) and then order someone to pronounce the Adhan [summons] for the prayer and then order someone to lead the prayer then I would go from behind and burn the houses of men who did not present themselves for the (compulsory congregational) prayer. By Him, in Whose Hands my soul is, if anyone of them had known that he would get a bone covered with good meat or two (small) pieces of meat present in between two ribs, he would have turned up for the ‘Isha’ prayer.’[fifth of the five daily prayers]
