When Allah enabled the Muslims to conquer Bilbeis in Egypt, they found therein the daughter of the Egyptian ruler al-Muqawqis, whose name was Armanoosah. She was close to her father, but she was visiting the city of Bilbeis with her servant Barbara in an attempt to escape marriage to Constantine the son of Heraclius, whom she did not want to marry. When some of the Muslim army managed to capture Armanoosah, Amr ibn Al-As, the Amir of Jihad in Egypt, gathered the Sahabah together and reminded them of the words of Allah:
BY ABU NAJAR ASH-SHAMI. REPRODUCED FROM KHILAFAH.COM It is reported in Sahih Muslim that Muawiya alias Ibn Salam narrated from Zaid bin Salam from Abu Salam (Mamthur Al-Habashi) who said that Hudaifa bin Yaman said, “I said “O Messenger of Allah!, no doubt, we had an evil time (i.e. the days of Jahiliyya or ignorance) and Allah brought us a good time (i.e. Islamic period) through which we are now living. Will there be a bad time after this good time?’ He ﷺ said: Yes. I said: ‘Will there be a good time after this bad time?’ He said: ‘Yes.’ I said: ‘Will there be a bad time after good time?’ He said: ‘Yes.’ I said: ‘How?’ Whereupon he ﷺ said, «يَكُونُ بَعْدِي أَئِمَّةٌ لاَ يَهْتَدُونَ بِهُدَاىَ وَلاَ يَسْتَنُّونَ بِسُنَّتِي وَسَيَقُومُ فِيهِمْ رِجَالٌ قُلُوبُهُمْ قُلُوبُ الشَّيَاطِينِ فِي جُثْمَانِ إِنْسٍ» “There will be leaders who will not be led by my guidance and who will not adopt my Sunnah.

(As-Saff, 61:4) The following is a translation of Dr Fadhel al Samarrai’s Tafseer of Surah Saff. It shows the importance of Muslim armies fighting to achieve Islamic interests (في سَبيلِهِ) and the importance of uniting in fighting as one strong, unified structure (بُنيانٌ مَرصوصٌ) rather than fighting as disunited nation states.
Abu Hurairah said: “By the One Whom there is no god but him, if Abu Bakr had not been appointed as Caliph then Allah would not have been worshipped.” 
“All pious Muslims well-read in the Hadith (the compiled sayings of the Prophet) firmly believe in the need to establish an Islamic State headed by a Muslim Caliph. This is mentioned twice in the Holy Quran and it’s central to the Islamic faith. No Muslim scholar would debate an Islamic state and the caliphate. Muslim Sunnis claim that the caliph should hail from Meccan notability. Shiite Muslims add that he must be from Ahl al-Bayt; a member of the prophet’s family.” (Sami Moubayed, Daily Telegraph, 23 Sep 2015)
