The Messenger (ṣallallāhu ʿalayhi wa-sallam) said in an authentic Ḥadīth, "The example of the believers is that they have mutual love for each other, they have mutual mercy for each other and they are like one body. If one part of the body suffers, the whole body suffers." Shaykh Muḥammd ibn Hādī al-Madkhali explains in great detail the meaning of this Ḥadīth and how it applies to the lives of the Muslims. (From the 2012 Dawrah in Medīnah, Saudi Arabia, hosted by the brothers at Salafī Publications.)
Ustadh Mūsá Richardson gives a clear and detailed explanation of this Ḥadīth, which is related by Abū Hurayrah. It teaches a very important sunnah that we can establish in our ṣalah and at other times. It has a very beautiful meaning and is full of benefits.
Shaykh Muḥammad ibn ʿAbd al-Waḥhāb al-Aqīl explains the Ḥadīth of the Messenger (ṣallallāhu ʿalayhi wa-sallam): "Whoever Allāh wants good for, He gives him understanding of the dīn." This Ḥadīth is so important that some of the scholars have written works based upon it. Shaykh Muḥammad ibn ʿAbd al-Waḥhāb al-Aqīl is one of the well-known scholars of Medīnah, and is a lecturer at the Islamic University of Menīnah. He wrote his PhD thesis on the topic: ʿAqīdah in the Belief in the Angels'. This lecture is translated by Abū Ḥakīm Bilāl Davis. (From the 2012 Madīnah Dawrah hosted by Salafī Publications.)
From the Five Pillars dawrah with the Shaykh, in Medinah (2012). Here, he explains the Ḥadīth of the Prophet (ṣallallāhu ʿalayhi wa-sallam), “Whosoever believes in Allāh and the last day then let him speak good or remain silent.” Shaykh ʿAbdullāh al-Bukhārī is a former student of Shaykh Muḥammad Amān al-Jāmī and is well known to the Salafi scholars. Translated by Abū Ḥakim Bilāl Davis.
On the authority of Ibn ʿUmar (raḍī Allāhu ʿʿʿanhumā) who said, "The Messenger of Allāh (ṣallallāhu ʿalayhi wa-sallam) took me by my shoulders and said: ‘Be in this world as if you are a stranger or a wayfarer.'’’
