Surah 2. Al-Baqara

As-Suddi narrated from Abu Malik and (also) from Abu Salih, from Ibn `Abbas, and (also) Murrah Al-Hamdani from Ibn Mas`ud and other Companions that this Ayah,

(In their hearts is a disease) means, `doubt', and,

(And Allah has increased their disease) also means `doubt'. Mujahid, `Ikrimah, Al-Hasan Al-Basri, Abu Al-`Aliyah, Ar-Rabi` bin Anas and Qatadah also said similarly. `Abdur-Rahman bin Zayd bin Aslam commented on,

(In their hearts is a disease), "A disease in the religion, not a physical disease. They are the hypocrites and the disease is the doubt that they brought to Islam.

(And Allah has increased their disease) meaning, increased them in shameful behavior.'' He also recited,

(As for those who believe, it has increased their faith, and they rejoice. But as for those in whose hearts is a disease, it will add disgrace to their disgrace.) (9:124-125) and commented, "Evil to their evil and deviation to their deviation.'' This statement by `Abdur-Rahman is true, and it constitutes a punishment that is compatible to the sin, just as the earlier scholars stated. Similarly, Allah said,

(While as for those who accept guidance, He increases their guidance and grants them their piety) (47:17).

Allah said next,

(Because they used to tell lies). The hypocrites have two characteristics, they lie and they deny the Unseen.

The scholars who stated that the Prophet knew the hypocrites of his time have only the Hadith of Hudhayfah bin Al-Yaman as evidence. In it the Prophet gave him the names of fourteen hypocrites during the battle of Tabuk. These hypocrites plotted to assassinate the Prophet during the night on a hill in that area. They planned to excite the Prophet's camel, so that she would throw him down the hill. Allah informed the Prophet about their plot, and the Prophet told Hudhayfah their names.

As for the other hypocrites, Allah said about them,

(And among the bedouins around you, some are hypocrites, and so are some among the people of Al-Madinah who persist in hypocrisy; you (O Muhammad ) know them not, We know them) (9:101), and,

(If the hypocrites, and those in whose hearts is a disease, and those who spread false news among the people in Al-Madinah do not cease, We shall certainly let you overpower them, then they will not be able to stay in it as your neighbors but a little while. Accursed, they shall be seized wherever found, and killed with a (terrible) slaughter) (33:60-61).

These Ayat prove that the Prophet was not informed about each and everyone among the hypocrites of his time. Rather, the Prophet was only informed about their characteristics, and he used to assume that some people possessed these characteristics. Similarly, Allah said,

(Had We willed, We could have shown them to you, and you should have known them by their marks; but surely, you will know them by the tone of their speech!) (47:30).

The most notorious hypocrite at that time was `Abdullah bin Ubayy bin Salul; Zayd bin Arqam - the Companion - gave truthful testimony to that effect. In addition, `Umar bin Al-Khattab once mentioned the matter of Ibn Salul to the Prophet , who said,

(I would not like the Arabs to say to each other that Muhammad is killing his Companions.)

Yet, when Ibn Salul died, the Prophet performed the funeral prayer for him and attended his funeral just as he used to do with other Muslims. It was recorded in the Sahih that the Prophet said,

(I was given the choice (to pray for him or not), so I chose.)

In another narration, the Prophet said,

(If I knew that by asking (Allah to forgive Ibn Salul) more than seventy times that He would forgive him, then I would do that.)
