Explanation

The reason for opposing the rebuilding of the Temple by Rehum and his associates was that they believed the city of Jerusalem was rebellious and wicked. They feared that if the city was rebuilt and its walls finished, the Jews would not pay tribute, customs, or tolls, which would impair the royal revenue. Additionally, they mentioned that the city had a history of rebellion and sedition against kings and provinces, leading to its destruction in the past. All of these prove that Rehum and his associates were intolerant to the people of Israel.

Hadith means words, actions and silent/tacit approval of the Prophet (S.A.W.)

*During the life time of the Prophet (S.A.W.) and even after his death, his companions (A???b) used to refer to him directly, when quoting his sayings.

*The successors ( T?bi c?n) followed suit as some of them used to quote the Prophet (S.A.W) through the companions while others would omit the intermediate authorities.

*Many companions of the Prophet (S.A.W.) committed themselves to the study of the Hadith.

*It has also been noted that prominent companions e.g. cAli, ibn Masc?d and ibn ‘Abb?s would advise the T?bic?n to learn the Hadith.

*The transmission of Hadith was passed down from generation to generation.

*Thousands upon thousands of people began to transmit ?adith

*Consequently, deliberate fabrication of A??d?th by various sects led to the revival of the study of Hadith.

*As time passed by, more reports were involved in each Isn?d, so the situation demanded strict discipline in the acceptance of A??d?th

*These led to the verification of authentic ?adith.

*Likewise, the science of <em>Matn </em>(text) took root.

*The science of Asm?’ ar-Rij?l came into study.

*The desire of the Muslims to follow the Sunnah of the Prophet (S.A.W.) also served as a factor.
