Is the Hadith, "Whoever says: 'I am pleased with Allah as my Lord, and with Islam as my religion, and with Muhammad (peace and blessings of Allah be upon him) as a Prophet,' will be guaranteed Paradise," authentic or weak?

The honorable companion Abu Sa'id Al-Khudri (may Allah be pleased with him) narrated from the Prophet (peace be upon him) that he said: "(Whoever says: 'I am pleased with Allah as my Lord, and with Islam as my religion, and with Muhammad as a Messenger,' Paradise will be guaranteed for him)." This chain of narration is sound and its narrators are trustworthy. A similar wording of this hadith (definition) is found in Sahih (definition) Muslim, with an addition: "(O Abu Sa'id, whoever is pleased with Allah as his Lord, and with Islam as his religion, and with Muhammad as a Prophet, Paradise will be guaranteed for him. Abu Sa'id was astonished by this, so he said: 'Repeat it for me, O Messenger of Allah.' He did so, then he said: 'And another thing, by which the servant is raised a hundred degrees in Paradise, the distance between each two degrees being like the distance between the heavens and the earth.' He asked: 'And what is that, O Messenger of Allah?' He replied: 'Jihad in the way of Allah, jihad in the way of Allah.')"

Ibn Al-Qayyim, in "Madarij Al-Salikin," explains that being pleased with Allah as Lord entails loving Him, fearing Him, hoping in Him, and relying upon Him. Being pleased with Islam as a religion entails submitting to its rulings. Being pleased with Muhammad as a Messenger entails complete obedience to him and following him, indicating that these matters are the foundation of religion and are difficult at the time of true trial.

Al-Ayni, in "Sharh Sunan Abi Dawud," states that "I am pleased with Allah as my Lord" means contentment with Him and sufficing with Him alone, without anyone else. "And with Islam as my religion" means not seeking any path other than Islam. "And with Muhammad as a Messenger" means believing in his being sent as a messenger.
