Abu Haatim al-Hadrami (may Allah preserve him) wrote:

“The sign used in writing for when omitting speech is (…). They are placed to indicate speech that is omitted from the quote, which the writer does not want to mention.

For example:

قال الزُّهْرِيِّ رحمه الله : (التَّمَسُّكُ بِالسُّنَّةِ نَجَاةٌ ،
وَالْعِلْمُ يُقْبَضُ قَبْضًا سَرِيعًا…)


As for omitting speech in verses of the Quran and Ahaadith, then it is best to say ayah or Hadith [at the end]. For example:

(حَافِظُوا عَلَى الصَّلَوَاتِ) (الآية)

Guard strictly (five obligatory) As-Salawat (the prayers) [2:238] (al-Ayah).

Our Shaikh Yahya al-Hajuri (may Allah preserve him) provided that benefit”.
