Who will be the first to be greeted by the Truth and receive his book in his right hand?

Matters of the Hereafter are from the Unseen, which can only be known through information from Allah or His Messenger. No authentic report has been transmitted regarding who will be given their book in their right hand or their left hand first. Rather, weak narrations have been reported concerning this, which cannot be relied upon. Such matters are not essential to know, nor do they entail any action. A person should ask about what benefits them in their religion and worldly life, for excessive questioning about matters that are not beneficial is blameworthy.
