1500 نُهِيَنا عن التَّكَلُّف
We were forbidden from adopting the attitude of affectation

عن عمر رضي الله عنه قال: نُهِيَنا عن التَّكَلُّف.

‘Umar (may Allah be pleased with him) reported: We were forbidden from adopting the attitude of affectation.

صحيح - ( رواه البخاري ). Sahih/Authentic. [Al-Bukhari]

يخبر عمر رضي الله عنه في هذا الحديث: أنهم "نهوا عن التَّكلف" والناهي هو رسول الله صلى الله عليه وسلم ؛ لأن الصحابي إذا قال: "نهينا" فإن هذا له حكم الرفع يعني كأنه قال: نهانا رسول الله صلى الله عليه وسلم عن التكلف. والتكلف: هو كل فعل وقول يحاول صاحبه الظهور به أمام الآخرين وليس فيه . فمثال القول: كثرة السؤال، والبحث عن الأشياء الغامضة التي لا يجب البحث عنها، والأخذ بظاهر الشريعة وقبول ما أتت به، وعن أنسٍ رضي الله عنه قال: كنَّا عند عمر وعليه قميصٍ في ظهرِه أربع رقاع، فقرأ (وَفَاكِهَةً وَأَبًّا)، فقال: هذه الفاكهة قد عرفناها، فما الأَب؟ ثم قال: "قد نهينا عن التكلّف". والفعل: كأن ينزل به ضَيف فيتكلف له بما يَشق عليه، بل وربما يحمله ذلك على الاستدانة وقد لا يجد لهذا الدين وفاء، فيلحق بنفسه الضرر في الدنيا والآخرة. فعلى المسلم أن لا يتكلف في الأمور، بل يجعل الأمور وسطا كما كان حاله صلى الله عليه وسلم لا يُمسك موجودًا ولا يتكلف معدومًا.
Any statement by a Companion denoting prohibition, the prohibition therein is attributed to the Prophet (may Allah's peace and blessings be upon him). In this case, ‘Umar (may Allah be pleased with him) reports that they were forbidden, i.e. the Prophet (may Allah's peace and blessings be upon him) forbade them, from adopting the attitude of affectation. Affectation here refers to any statement or action that is not natural and that is intended to impress others. Affectation in statements is, for example, by asking too many questions and searching for obscure things that should not be looked for, instead of following and accepting the explicit commands of Shariah. Anas (may Allah be pleased with him) reported: "We were with ‘Umar and he was wearing a garment that had four patches. He recited from the Qur'an: {fruits and abba} [Sūrat ‘Abas: 31]. He remarked that he knew ''fruits'' and wondered what ''abba'' means. However, he said: "We were forbidden from adopting the attitude of affectation." Affectation in actions is when one overburdens himself by trying, for example, to entertain his guest beyond his financial means. One might even take a loan that he cannot later settle, thereby doing himself harm in life and in the Hereafter. Hence, the Muslim should not be pretentious, rather he should take a moderate approach to all things following the example of the Prophet (may Allah's peace and blessings be upon him) who neither withheld something available, nor pretended to have something unavailable.

النهي عن التَّكلف والحَثِّ على البُعد عنه في كلِّ شيء.
We are prohibited from affectation and urged to keep away from it in everything.
