The love for Allah is attained by following the Sunnah (way/practice) of Prophet Muhammad (peace be upon him).
Quoting the Quran: "If you love Allah, then follow me."
The footsteps of the Prophet (PBUH) lead to Paradise and bring connection to Allah.
Pious predecessors (Awliya Allah) had intense love for the Prophet (PBUH) and strictly adhered to his Sunnah.
An anecdote about a senior scholar (Hazrat Hakim Akhtar Sahib) kissing a shawl bought from Madinah, despite it being made in China, because it was touched by the blessed air of Madinah.
Another anecdote about Hazrat Qadiani Sahib refusing to wear green slippers out of extreme reverence for the green dome of Madinah.
These acts emphasize that respect and love for anything associated with the Prophet (PBUH) or Madinah is a matter of the heart, not just jurisprudence.
Even merely uttering the name "Madinah" brings immense spiritual pleasure due to its blessed status.
A person criticizing the cats of Madinah was told in a dream to leave if he disliked them, highlighting the sanctity of everything in Madinah.
The contentment and peace people seek in the world can truly be found by following the system and Sunnah of Madinah.
A person who becomes a 'slave' (devoted follower) of Madinah by embodying its ways will be free from the sorrows of both this world and the hereafter.
