Surah Al-Baqarah (The Cow), Verse 214

اَمْ حَسِبْتُمْ اَنْ تَدْخُلُوا الْجَنَّةَ وَلَمَّا یَاْتِكُمْ مَّثَلُ الَّذِیْنَ خَلَوْا مِنْ قَبْلِكُمْ مَسَّتْهُمُ الْبَاْسَآءُ وَالضَّرَّآءُ وَزُلْزِلُوْا حَتّٰی یَقُوْلَ الرَّسُوْلُ وَالَّذِیْنَ اٰمَنُوْا مَعَهٗ مَتٰی نَصْرُ اللّٰهِ اَلَاۤ اِنَّ نَصْرَ اللّٰهِ قَرِیْبٌ ۟

Am hasibtum an tadkhulul jannata wa lammaa yaa-tikum masalul lazeena khalaw min qablikum massathumul baasaaa'u waddarraaaa'u wa zulziloo hattaa yaqoolar Rasoolu wallazeena aamanoo ma'ahoo mataa nasrul laah; alaaa inna nasral laahi qareeb

“Or do ye think that ye shall enter the Garden (of bliss) without such (trials) as came to those who passed away before you? they encountered suffering and adversity, and were so shaken in spirit that even the Messenger and those of faith who were with him cried: "When (will come) the help of Allah?" Ah! Verily, the help of Allah is (always) near!”
