The second source of Tafseer is the speech of the Messenger of Allah (S.A.W.W). If someone asks about the best methods of Tafsir, we reply that the best method is to explain the Qur'an with the Qur'an itself. When one does not find it easily, he should refer to the Sunnah of Prophet Muhammad (S.A.W.W) because its purpose is to explain the Qur'an and elaborate its meanings. Allah said,
. ‘And We have also sent down unto you (O Muhammad SAW) the reminder and the advice (the Quran), that you may explain clearly to men what is sent down to them, and that they may give thought.’ (An Nahl 16:44) ‘This is why the Messenger of Allah (S.A.W.W) said,
‘The Sunnah was a revelation from Allah just as the Qur'an, although it is not recited as the Qur'an is recited.’
There are numerous examples of explanation of the Qur'an by the Prophet, who either asked the Angel Gabriel for matters that needed some explanation. Here one example may suffice:
'And eat and drink until the white thread of dawn appears to you distinct from its black thread. . .' (2: 187). Narrated 'Adi b. Hâtim:
I said: 'O Allah's Apostle! What is the meaning of the white thread distinct from the black thread? Are these two threads?' He said: 'You are not intelligent, if you watch the two threads'. He then added, 'No, it is the darkness of the night and the whiteness of the day'. An example where the Qur’ān is clearly explained by the Prophetic tradition (hadīth) is in the verse in chapter 10:26 “Those who have done righteousness, for them will be the best reward (paradise) and something more.” This ‘something more’ has been explained to mean seeing His face based upon the authentic Prophetic tradition reported by Abu Musa and Ubay ibn Ka’b and recorded by Ibn Jarīr and Ibn Abi Hātim. There is also a hadīth in Ṣaḥīḥ Muslim (no.449) narrated by Ṣuhaib bin Sinān from the Prophet (peace be upon him). Within this latter hadīth is the statement of the narrator that the Prophet (peace be upon him) said, “then the covering will be removed and they will not have been given anything more beloved to them than looking at their Lord.” This interpretation is in harmony with other verses in the Qur’ān that confirm the believers seeing Allāh on the Day of Judgement such as, “Some faces that Day shall be radiant, Looking at their Lord (Allāh)” [75:22-23:].
