How sound is the Hadith which mentions that those who put their trust in Allah will enter Paradise without reckoning, and what is their reward in this world and the Hereafter?

"Seventy thousand from the Ummah of Muhammad (peace be upon him) will enter Paradise without reckoning. They are those who 'do not seek Ruqyah, nor do they believe in evil omens, nor do they cauterize, and upon their Lord they rely.' Among the rewards for those who rely on Allah are gaining Allah's love, achieving and perfecting faith, Allah's sufficiency for them, and provision from sources they do not anticipate."
