Asking for more than had been asked before
Ibrāhīm had asked for Makkah. He asked for twice that.
اللَّهُمَّ اجْعَلْ بِالْمَدِينَةِ ضِعْفَىْ مَا بِمَكَّةَ مِنَ الْبَرَكَةِ
Allāhumma-jʿal bi-l-madīnati ḍiʿfay mā bi-makkata mina-l-barakah.
“O Allah, place in Madinah twice the blessing You placed in Makkah.”
The full narration
Anas b. Malik (Allah he pleased with him) reported that Allah's Messenger (ﷺ) said:O Allah, increase in Medina twice the blessings (Thou showered) on Mecca
