Allah, the exalted, says in the noble Quran as such:

مُّحَمَّدٌ رَّسُولُ اللَّـهِ ۚ وَالَّذِينَ مَعَهُ أَشِدَّاءُ عَلَى الْكُفَّارِ رُحَمَاءُ بَيْنَهُمْ ۖ

Muhammad is the Messenger of Allah; and those with him are forceful against the disbelievers, merciful among themselves [48:29].

How can the muslims be "forceful" among disbelievers and "merciful" among themselves in the modern world which is referred to as the "Global Village" ?
