The prohibition of going to excessive trouble for a guest

It is narrated from Sayyiduna Salman al-Farisi (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) forbade us from going to (excessive) trouble for a guest.

It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The most enviable of people in my sight is a believer who is light of burden, who has an ample share of prayer, who worshipped his Lord in the best manner and obeyed Him in private as well, who remained obscure among people so that fingers were not pointed at him, whose provision was just sufficient for his needs (kafaf), and who was patient with that." Then the Messenger of Allah (peace and blessings be upon him) flicked his blessed finger and said: "His death came quickly, the women weeping over him were few, and his inheritance was very little."
According to the people of Syria, this chain is authentic by their standard, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Successful is the one who accepted Islam, was given provision just sufficient for his needs (kafaf), and whom Allah made content with what He gave him."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
