(Fatwa: 260/222/M=2/1439)
(1) Yes, you can perform nafl tawaf on behalf of your family, friends and relatives though they are alive, they will receive its reward.
….من صام أو صلى أو تصدق وجعل ثوابه لغيره من الأموات والأحياء جاز ويصل ثوابها إليهم عند أهل السنة والجماعة … (بدائع)
(2) Performing tawaf around the House of Allah carries lots of reward and great virtues. It is recorded in one Hadith: “Whoever performs Tawaf around this House seven times, then it is as if he freed a slave.”
It is recorded in another Hadith: “Whoever performed Tawaf around the House fifty times, he will be as free of his sins as the day his mother bore him.”
من طاف سبعاً فهو كعدل رقبة .(نسائي)
من طاف بالبيت خمسين مرة خرج من ذنوبه كيوم ولدته امه (ترمذى)
Allah knows Best!
