مناسك حج - مكارم شيرازى، ناصر - الصفحة ١٣٣ - Doubt in Amount of Tawaf
Article ٢١٩-" Tawaf" and" prayer of obligatory Tawaf" can be performed anytime in night and day; even it has no duress to perform this prayer in the time of sunrise or sunset.
Article ٢٢٠- Whenever a person cannot perform the prayer of Tawaf immediately after Tawaf because of the presence of an obstacle like invalidation of ablution for prayer, impurity of the body or clothes or congestion of crowds for performing daily congregation prayers, he/ she performs it after that obstacle has removed and both" Tawaf" a and" its prayer" are correct.
Article ٢٢١- It is obligatory for any Mukallaf( accountable; a Muslim who has reached the age of puberty )to learn the recitation of the prayer; it means that he/ she recites Hamd and Sura and other recitations of the prayer correctly, but if this person couldnt learn that completely after necessary tries because of illiteracy or other reasons, that amount which he/ she can recite is enough, but if it is possible for him/ her to learn but he/ she does not try because of insouciance then he/ she is performing a sin; but if there is not enough time for learning then he/ she should perform as much as he/ she has learned and it is not necessary to take a proxy, and performing the prayer of Tawaf in congregation has problem.
