They also commemorate the anniversaries of their death.

They also commemorate the anniversaries of their death. On such ceremonies, they mention their virtues, merits, and exemplary stances, which have been authentically reported by the Holy Qur'an that mentions, praises, and draws the attentions to the virtues of the Prophets and Messengers so that people may follow them, learn lessons from them, and gain true guidance.

Of course, in such celebrations, they refrain from committing forbidden acts; such as unlawful mixture of opposite sexes, eating or drinking forbidden things, exaggeration in praise and applause or other deeds that contradict the spirit of the holy Islamic law, go beyond its acknowledged regulations, are incongruous with the sacred Qur'anic texts and the authenticated Sunnah, or are incompatible to a general rule, which has been truly inferred from the Holy Qur'an and Sunnah in a sound way.

(33) The Ja`fariyyah Shi`ah have recourse to a number of books comprising Prophetic traditions and the traditions narrated from his Immaculate Household, such as ‘al-Kafi’ by Shaykh al-Kulayni, a trustworthy scholar, and ‘man-la-yahzaruhu’l-faqih’ by Shaykh al-saduq, and ‘Tahdhib al-Ahkam’ and ‘al-IstibSar’ by Shaykh al-tusi. These are invaluable reference books in the field of hadith.

Albeit that these books comprise authentic narrations, neither their compilers nor the Ja`fariyyah Shi`ah call them Sahih (pl.

Sihah), that is fully authentic; therefore, the Shi`ah do not consider all narrations mentioned in these books authentic; rather they accept authenticated narrations and reject the ones which are inauthentic, unsound, or do not accord with the science of investigating reported traditions (`ilm al-dirayah), biography of reporters (`ilm al-rijal) or the rules of the science of hadith.

(34) In the fields of doctrines, jurisprudence, supplications, and ethics, the Ja`fariyyah Shi`ah have recourse to other books which contain various narrations reported from the Holy Imams, such as ‘Nahj al-Balaghah’ that is a collection of the sermons, epistles, and aphorisms of Imam `Ali (a.s) compiled by al-Sharif al-Razi; ‘Risalat al-Huquq (The Treatise on Rights)’ and ‘al-sahifah al-Sajjadiyyah’ (also known as the psalms of Islam) by Imam `Ali ibn al-Husayn Zayn al-`abidin (a.s); ‘al-sahifah al-`Alawiyyah’ comprising the prayers of Imam `Ali (a.s); and Shaykh al-saduq’s books of ‘`Uyun Akhbar al-Riza’, ‘al-Tawhid’, ‘al-KhiSal’, ‘`Ilal al-Shara'i`’, and ‘Ma`ani al-Akhbar’.
