One of the most fundamental issues of the Shiites' beliefs in the field of Imamate is that "the earth will not remain empty from hujja". Verses of the Holy Quran and hadiths of the infallible (AS) as well as important works of the Shiite leaders have been put forward to prove this belief. This important rule is referred to as "commandment connection”. The verses referring to the placement of the Caliph of God on earth, or the presence of divine witnesses and warnings among the nations, refer to this rule. It is also backed by numerous narrations from the Ahl al-Bayt (AS), which crosses the spiritual boundary. Given the credibility and acceptability of Nahj al-Balagha among many Islamic sects, the explanation of this issue in Nahj al-Balagha becomes doubly important. By examining the words of Nahj al-Balagha, it is revealed that in the phrases of the first sermon, sermons 87, 88, 97, 237, and utterance 147, this matter has been mentioned.
