Is the Hadith "A person will be recompensed with a seat in Paradise if he is content with the least provision" authentic?

The hadith mentioned in the question: "Whoever satisfies his desires in this world, will be prevented from his desires in the Hereafter. And whoever casts his eyes upon the adornment of the extravagant, will be disgraced in the dominion of the heavens. And whoever patiently endures a severe struggle with beautiful patience, Allah will house him in Al-Firdaws wherever He wills," is weak and not authentic. It contains more than one flaw in its chain of narration (sanad).

What has been authentically reported from the Prophet, peace and blessings be upon him, regarding the virtue of contentment, suffices instead. Such as: "Successful is he who embraces Islam, is provided with just enough, and Allah makes him content with what He has given him," and "Blessed is he who is guided to Islam, whose sustenance is sufficient, and with which Allah makes him content."
