عَنْ أَبِي عَبْدِ اللَّهِ النُّعْمَانِ بْنِ بَشِيرٍ رَضِيَ اللهُ عَنْهُمَا قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ: «إِنَّ الْحَلاَلَ بَيِّنٌ وَإِنَّ الْحَرَامَ بَيِّنٌ، وَبَيْنَهُمَا أُمُورٌ مُشْتَبِهَاتٌ لاَ يَعْلَمُهُنَّ كَثِيرٌ مِنَ النَّاسِ، فَمَنِ اتَّقَى الشُّبُهَاتِ اسْتَبْرَأَ لِدِينِهِ وَعِرْضِهِ، وَمَنْ وَقَعَ فِي الشُّبُهَاتِ وَقَعَ فِي الْحَرَامِ... أَلاَ وَإِنَّ فِي الْجَسَدِ مُضْغَةً إِذَا صَلَحَتْ صَلَحَ الْجَسَدُ كُلُّهُ، وَإِذَا فَسَدَتْ فَسَدَ الْجَسَدُ كُلُّهُ، أَلاَ وَهِيَ الْقَلْبُ».
Kutoka kwa Abu Abdullah an-Nu'man bin Bashir (Radhi za Allah ziwe juu yao) amesema: Nilimsikia Mjumbe wa Allah akisema: "Hakika halali iko wazi na haramu iko wazi, na baina ya hivyo viwili kuna mambo yenye utata ambayo watu wengi hawayajui. Basi mwenye kujiepusha na mambo yenye shaka, ameweka salama dini yake na heshima yake. Na mwenye kuangukia katika shaka ataangukia katika haramu... Jueni kuwa ndani ya mwili kuna kipande cha nyama, kikitengemaa basi mwili mzima unakuwa mwema, na kikiharibika basi mwili mzima unaharibika, jueni kwamba hicho ni moyo."
On the authority of Abu 'Abdullah al-Nu'man bin Bashir (may Allah be pleased with both of them) who said: I heard the Messenger of Allah say: "Truly, what is lawful is clear and what is unlawful is clear, and between them are matters of doubt which many people do not know. So whoever guards against doubts clears himself in regard to his religion and his honor, but whoever falls into doubts falls into what is unlawful... Truly, there is a piece of flesh in the body which, if it is sound, the whole body is sound, and if it is diseased, the whole body is diseased. Truly, it is the heart."
Wema wa mwanadamu unatokana na usafi na unyofu wa moyo wake.
Kujiepusha na mambo yenye utata huweka heshima na dini ya Muislamu salama.
Kutunza moyo ndio msingi wa kudhibiti viungo vyote vya mwili.
