Hakika, mtu anayechunguza wajibu wa Mwenyezi Mungu ataona kwamba baadhi yake ni wajibu wa mtu binafsi na baadhi yake ni wajibu wa pamoja. Fardh ‘ayni (wajibu wa mtu binafsi) ni wajibu ambao lazima utekelezwe na kila mukallaf (mtu mwenye dhima ya kisheria) mwenyewe. Ikiwa Muislamu atauacha wajibu huu, basi hatakuwa huru na dhambi, hata kama Waislamu wote wamekwisha kuutekeleza. Na ikiwa atautekeleza wajibu huo wakati Waislamu wote wameupuuza, basi atakuwa huru na dhambi na lawama mbele ya Allah 􀀬. Hii ina maana kwamba ni lazima kwa kila Muislamu kutafuta wajibu wa mtu binafsi na kuushikamana nao, ili aondokane na hatia na kuitua dhamiri yake mbele ya Muumba wa wajibu. Vilevile, yale yaliyosemwa kuhusu wajibu wa mtu binafsi ndivyo yalivyo pia kuhusu makatazo, mradi yanahusu mtu binafsi. Hii ina maana kwamba Muislamu anapaswa kuswali, kufunga Ramadhani, kuhiji Nyumba Tukufu anapoweza, kutoa zakah wakati mali yake inafikia nisaab (kiwango cha chini ambacho zakah inawajibika juu yake), kuwatunza wazazi wake, kula halali na nzuri; kujiepusha na kula maovu na haramu, na kujiepusha na zinaa, uongo na ghiba, na mambo mengine kama hayo, ambayo Muislamu lazima ayauliize. Hivyo atafanya kitendo chochote ikiwa ni ma‘ruf, na atajiepusha nacho ikiwa ni munkar.

Indeed, the one who examines the divine obligations will find that some of them are individual and some are collective. The fard ‘ayni (individual obligation) is the obligation which must be undertaken by every mukallaf (legally responsible person) by himself. If a Muslim abandons this obligation, then he would not be free of the sin, even if all the Muslims had undertaken it. If he undertook the obligation while all the Muslims neglected it, then he would be free of the sin and blame before Allah 􀀬. This means that it is incumbent on every Muslim to search for the individual obligations and adhere to them, so as to be absolved from guilt, and to relieve his conscience before the Creator of obligations. Likewise, what has been said about the individual obligations is also the case regarding the prohibitions, as long as they relate to the individual. This means that the Muslim has to perform the salah, fast in Ramadan, make pilgrimage to the Sacred House when he can, pay the zakah when his wealth reaches the nisaab (the minimum amount above which zakah is due), look after his parents, eat the halaal and good; abstain from eating the evil and haraam and abstain from zina (adultery), lying and backbiting, and other such things, which the Muslim must inquire about. Thus he will undertake any action if it is ma’roof and abstain if it is munkar.
