Likewise there are four conditions which are compulsory but do not make the salat void if, for example, one unintentionally does not fulfill them: (1) qira'ah (the reading of Surah al-Hamd and one other complete surah); (2) dhikr, tashahud and the final salam. One must be Still and in a state of remembrance throughout the prayer. Adhan and iqamah before the start of the prayer are both strongly desirable (indeed almost compulsory).

The following invalidate the prayer: anything which breaks one's state of wudu', turning one's back on the qiblah, and excessive movement. Any other action (which is not a fundamental part of the prayer) such as talking, laughing, weeping, looking to the right or left, eating or drinking invalidate the prayer if done intentionally. To purify oneself, ready for any act of 'ibadat (such as prayer), one must make either wudu' (the minor purification) or ghusl (the major purification).

In case of absence of water, or for some other reason like illness, unbearable cold, shortness of time, when it is not possible to do either of these two acts of purification, their substitute is "tayammum" (cf. the Qur'an which indicates this method of purification: fa tayammamu sa'idan tayyiban - so perform tayammum on pure earth - Surah al-Ma'idah). The scholars of jurisprudence and the lexicographers give various meanings for the word "sa'id".

Some of them say it only means dust, and some say. that it means all kinds of pound (including sand, fragments of rocks, stones, and mineral substances). We have limited our ascription of salat to fundamentals: more detailed studies may be found in numerous other works. 2. Sawm (Fasting) According to the Shi'a faith, sawm (plural siyam), fasting, is a pillar of the Islamic code. There are four kinds of siyam: wajib (compulsory), mustahabb (recommended), haram (forbidden) or makruh (undesirable).

The fasts made incumbent by the shari'ah (code of religion) are those of the Holy month of Ramadan. Other fasts become incumbent for some specific reason, for instance "sawm kaffarah" (the penalty fast), "badal"(in lieu of sacrificing an animal), in lieu of someone else, "nadr" (as a vow, or oath). The fasts of the months of Rajab and Sha'ban are desirable as well as other fasts too numerous to mention in this brief work.
