Strict Orders for Observance of Obligatory Salat

Ibn 'Umar (May Allah be pleased with them) reported:
The Messenger of Allah ﷺ said, "Islam is based on five (pillars): testifying that there is no true god except Allah and that Muhammad ﷺ is His slave and Messenger; performing of Salat (Iqamat-as-Salat), the payment of Zakat; performing Hajj (pilgrimage) to the House [of Allah (Ka'bah)]; and Saum (fasting) during the month of Ramadan."

[Al-Bukhari and Muslim].

وعن ابن عمر رضي الله عنهما قال: قال رسول الله ﷺ: " بني الإسلام على خمس: شهادة أن لا إله إلا الله وأن محمدًا رسول الله، وإقام الصلاة، وإيتاء الزكاة، وحج البيت، وصوم رمضان" ((متفق عليه)).

Ibn 'Umar (May Allah be pleased with them) reported:
The Messenger of Allah ﷺ said, "I have been commanded to fight against the people till they testify La ilaha illAllah (There is no true god except Allah) and that Muhammad ﷺ is His slave and Messenger, and to establish As-Salat (Iqamat-as-Salat), and to pay Zakat; and if they do this, then their blood and property are secured except by the rights of Islam, and their accountability is left to Allah."

[Al-Bukhari and Muslim].

وعنه قال: قال رسول الله ﷺ "أمرت أن أقاتل الناس حتى يشهدوا أن لا إله إلا الله وأن محمدًا رسول الله، ويقيموا الصلاة ويؤتوا الزكاة، فإذا فعلوا ذلك، عصموا مني دماءهم وأموالهم إلا بحق الإسلام، وحسابهم على الله" ((متفق عليه)).

Mu'adh (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ sent me as a governor to Yemen and (at the time of departure) he instructed me thus: "You will go to people of the Scripture (i.e., the Jews and the Christians). First of all invite them to testify that La ilaha ill Allah (There is no true god except Allah) and that Muhammad ﷺ is His slave and Messenger; and if they accept this, then tell them that Allah has enjoined upon them five Salat (prayers) during the day and night; and if they accept it, then tell them that Allah has made the payment of Zakat obligatory upon them. It should be collected from their rich and distributed among their poor; and if they agree to it, don't take (as a share of Zakat) the best of their properties. Beware of the supplications of the oppressed, for there is no barrier between it and Allah."

[Al-Bukhari and Muslim].

وعن معاذ رضي الله عنه قال: بعثني رسول الله ﷺ إلى اليمن فقال: "إنك تأتي قومًا من أهل الكتاب، فادعهم إلى شهادة أن لا إله إلا الله وأني رسول الله، فإن هم أطاعوا لذلك، فأعلمهم أن الله تعالى افترض عليهم خمس صلوات في كل يوم وليلة، فإن هم أطاعوا لذلك، فأعلمهم أن الله تعالى افترض عليهم صدقة تؤخذ من أغنيائهم فترد على فقرائهم، فإن هم اطاعوا لذلك، فإياك وكرائم أموالهم واتقِ دعوة المظلوم فإنه ليس بينها وبين الله حجاب" ((متفق عليه)).

Jabir (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "Between a man and disbelief and paganism is the abandonment of Salat (prayer)."

[Muslim].

وعن جابر رضي الله عنه قال: سمعت رسول الله ﷺ يقول: "إن بين الرجل وبين الشرك والكفر ترك الصلاة" ((رواه مسلم)).

Buraidah (May Allah be pleased with him) reported:
Messenger of Allah ﷺ said, "That which differentiates us from the disbelievers and hypocrites is our performance of Salat. He who abandons it, becomes a disbeliever."

[At-Tirmidhi].

وعن بريدة رضي الله عنه عن النبي ﷺ قال: "العهد الذي بيننا وبينهم الصلاة، فمن تركها فقد كفر" ((رواه الترمذي وقال: حديث حسن صحيح)).

Shaqiq bin 'Abdullah reported:
The Companions of the Messenger of Allah ﷺ did not consider the abandonment of any action as disbelief except neglecting Salat.

[At- Tirmidhi].

وعن شقيق بن عبد الله التابعي المتفق على جلالته رحمه الله قال: كان أصحاب محمد ﷺ لا يرون شيئًا من الأعمال تركه كفر غير الصلاة. ((رواه الترمذي في كتاب الإيمان بإسناد صحيح)).

Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "The first of man's deeds for which he will be called to account on the Day of Resurrection will be Salat. If it is found to be perfect, he will be safe and successful; but if it is incomplete, he will be unfortunate and a loser. If any shortcoming is found in the obligatory Salat, the Glorious and Exalted Rubb will command to see whether His slave has offered any voluntary Salat so that the obligatory Salat may be made up by it. Then the rest of his actions will be treated in the same manner."

[At- Tirmidhi].

وعن أبي هريرة رضي الله عنه قال: قال رسول الله ﷺ: "إن أول ما يحاسب به العبد يوم القيامة من عمله صلاته، فإن صلحت، فقد أفلح وأنجح، وإن فسدت، فقد خاب وخسر، فإن انتقص من فريضته شيئًا، قال الرب، عز وجل: انظروا هل لعبدي من تطوع، فيكمل منها ما انتقص من الفريضة؟ ثم يكون سائر أعماله على هذا" ((رواه الترمذي وقال حديث حسن)).
