Glad tidings of martyrdom to Hadhrat Uthman | Glad tidings of Jannah

The Holy Prophet (Sallallahu alaihi wa sallam) is aware of the events and conditions of every follower of His.  This is the reason why He (Sallallahu alaihi wa sallam) gave glad tidings of martyrdom to Hadhrat ‘Uthman (May Allah be well pleased with him).  There is a Hadith in Sahih Bukhari:

Translation: It has been narrated on the authority of Hadhrat Anas Bin Malik (May Allah be well pleased with him), he said that the Holy Prophet (Sallallahu alaihi wa sallam) graced the mountain of Uhud along with Hadhrat Abu Bakr Siddiq, Hadhrat Umar Farooq and Hadhrat Uthman (May Allah be well pleased with them).  The mountain of Uhud started swaying out of happiness. The Holy Prophet (Sallallahu alaihi wa sallam) tapped it with His foot and said: Steady o mountain! The Prophet is on you and 1 faithful (Siddiq) and 2 martyrs (Shaheed).  (Sahih Bukhari, Hadith No: 3686)

Imam Jalaluddin Suyuti (May Allah shower His mercy on him) has narrated a Hadith on the authority of Ibn Asaker:

Translation: It has been narrated on the authority of Hadhrat Zaid bin Thabit (May Allah be well pleased with him), he said:  I heard the Holy Prophet (Sallallahu alaihi wa sallam) say: Uthman passed by me.  At that time, an angel was present before me.  He said: Hadhrat ‘Uthman is a martyr.  His own people will martyr him. All us angels are modest before ‘Uthman.  (Tarikh Ul Khulafa, Vol. 1, Pg. No. 62)

Glad tidings of Jannah

Allah Most High has promised Jannah for all the Companions, as is mentioned in the Holy Quran:

And what is the matter with you that you do not spend in the Way of Allah whereas the ownership of the heavens and the earth belongs to Allah alone (you are merely His vicegerents)? Those of you who spent (their wealth in the Way of Allah before Makkan Victory) and fought, they (and you) cannot be equal. They are far higher in rank than those who spent their wealth afterwards and fought. But Allah has promised the most pleasing end (i.e. Paradise) to all in the Hereafter. And Allah is Well Aware of what you do. Surah Hadeed (57:10)

Hadhrat ‘Uthman received special tidings of Jannah apart for this general one, as given in this Hadith of Kanz Ul Ummal:

Translation: It is narrated on the authority of Hadhrat Anas bin Malik (May Allah be well pleased with him), he says that the Holy Prophet (Sallallahu alaihi wa sallam) went to a orchard.  A person came and knocked on the door.  The Holy Prophet (Sallallahu alaihi wa sallam) said:  O Anas!  Get up and open the door.  Give him the glad tidings of Jannah and the caliphate after me.  I asked:  O Prophet of Allah (Sallallahu alaihi wa sallam)!  Should I tell him all this?  He said: Yes, tell him.  When I came outside, I saw that it was Hadhrat Abu Bakr Siddiq (May Allah be well pleased with him).  I told him:  There are glad tidings of Jannah for you and glad tidings of caliphate after the Holy Prophet (Sallallahu alaihi wa sallam).

Then another person came and knocked at the door.  The Holy Prophet (Sallallahu alaihi wa sallam) said:  O Anas!  Get up and open the door for him.  Give him glad tidings of Jannah and of the caliphate after Abu Bakr.  I asked:  O Prophet of Allah (Sallallahu alaihi wa sallam)!  Should I tell him this? He said:  Yes, tell him.  When I came out I saw that it was Hadhrat ‘Umar (May Allah be well pleased with him).  I told him:  There are glad tidings of Jannah for you and of the caliphate after Hadhrat Abu Bakr (May Allah be well pleased with him).

Then yet another person knocked.  The Holy Prophet (Sallallahu alaihi wa sallam) said:  Anas, get up and open the door for him.  Give him glad tidings of Jannah and of the caliphate after Abu Bakr and ‘Umar.  Also give him the glad tidings of martyrdom.  When I came out, I saw it was Hadhrat ‘Uthman (May Allah be well pleased with him).  I told him so.  Then Hadhrat ‘Uthman (May Allah be well pleased with him) came to the Holy Prophet (Sallallahu alaihi wa sallam) and said:  O Prophet of Allah (Sallallahu alaihi wa sallam)! By Allah, I have never sung and have never done any indecent thing.  From the time I gave my pledge to you, I have never touched my private parts with that hand.  The Holy Prophet (Sallallahu alaihi wa sallam) said:  O ‘Uthman, it is for this reason you have received such high stations.  (Kanz Ul Ummal, Hadith No. 36267)
