Riyad as-Salihin, 157

'Irbad bin Sariyah (May Allah be pleased with him) reported:

One day Messenger of Allah (ﷺ) delivered us a very eloquent Khutbah on account of which eyes shed tears and hearts were full of tears. A man said: "O Prophet (ﷺ) of Allah, this is as if it were a parting advice. So advise us". He (ﷺ) said, "I admonish you to fear Allah, to listen and obey even if an Abyssinian slave is appointed as your leader. Because whosoever among you shall live after me, will see much discord. So hold fast to my Sunnah and the examples of the Rightly- Guided Caliphs who will come after me. Adhere to them and hold to it fast. Beware of new things (in Deen) because every Bid'ah is a misguidance". <b>[Abu Dawud and At- Tirmidhi, who categorized it as Hadith Hasan Sahih]</b>.

الثاني‏:‏ عن أبي نجيح العرباض بن سارية رضي الله عنه قال‏:‏ ‏"‏وعظنا رسول الله صلى الله عليه وسلم موعظة بليغة وجلت منها القلوب وذرفت منها العيون، فقلنا‏:‏ يا رسول الله كأنها موعظة مودع فأوصنا‏.‏ قال‏:‏ ‏"‏أوصيكم بتقوى الله ، والسمع والطاعة وإن تأمر عليكم عبد حبشي، وإنه من يعش منكم فسيرى اختلافاً كثيراً‏.‏ فعليكم بسنتي وسنة الخلفاء الراشدين المهديين، عضوا عليها بالنواجذ، وإياكم ومحدثات الأمور فإن كل بدعة ضلالة‏"‏ ‏(‏‏(‏رواه أبو داود، والترمذي وقال ‏:‏ حديث حسن صحيح‏)‏‏)‏‏.‏

<b>Guidance from the Hadith:</b><br> 1) It instructs commitment to piety of Allah, Glorified and Exalted, in secret and in public.<br> 2) It is obligatory to obey the leaders because this protects against tribulations. However, they are to be obeyed only in matters approved by the Sharia. As for matters that violate the Sharia, no one is obliged to obey it.<br> 3) It instructs holding tight to the Sunnah of the Messenger (may Allah’s peace and blessings be upon him) and the the practice of the rightly-guided Caliphs after him.<br> 4) Every religious innovation is misguidance even if its doer believes it to be good, because all goodness lies in following the guidance of the Prophet (may Allah’s peace and blessings be upon him).<br> <br> <br> <br> <b>Words in the Hadith:</b><br> Be pious to Allah: take protection against the punishment of Allah by complying with the commands and refraining from the prohibitions.
