Shaykh Khalid Kurdi (Allah have mercy on him) said that in the blessed city of Madinah he requested a Yemeni Shaykh for dua and advice prior to departing for Makkah mukarramah.

The Yemeni Shaykh made dua for him and instructed,

‘Do not waste time there.

Use it effectively in tawaf, supererogatory salah, recitation of Holy Quran, remembrance of Allah (dhikr) or performing your missed (qaza) salah.

Moreover, under all circumstances avoid all (even in your thoughts), criticism of, and argumentation with, anyone in the Holy precinct of Makkah.

Be busy with your own work. ‘
