أَمْ هَبَّـتِ الرِّيْحُ مِنْ تِلْقَآءِ كَاظِمَـةٍ وأَوْمَضَ الْبَرْقُ فِي الظَّلْماءِ مِنْ إِضَمِ

2/2. Or is it because of the breeze blowing from Kaazimah? Or is it because of the lightning (that has) struck in the darkness of the night from the valley of Idham?

Kaazimah is either:

1. Madinah Munawwarah - Madinah is called Kaazimah since its people have control and forbearance. (كاظم اهله)

2. A place near Madinah Munawwarah.

3. A river close to Madinah Munawwarah. It is possible that the place was initially out of the vicinity of Madinah Munawwarah and was later incorporated into Madinah Munawwarah.

Idham – This is a valley close to Madinah Munawwarah. Mention is made of this valley in certain Ahaadeeth.
Abu Hurayrah RadhiAllaahu Anhu said, “The molars of a disbeliever will be like Uhud on the Day of Judgement….and it has been said, ‘His stomach will be like the Valley of Idham.” (Mustadrak vol. 4-page 638 no. 8761)

Rasulullaah SalAllaahu Alaihi Wasallam had a wrestling match thrice with Rukaanah, a famous wrestler in this very valley and defeated him all three times, which led to his acceptance of Islam. (Dalaailun-Nubuwwah of Bayhaqi vol. 6 page 250, Khasaaisul-Kubraa vol. 1 page 129)
Once, Rasulullaah SalAllaahu Alaihi Wasallam sent a battalion to this area. (As-Sunanul-Kubraa of Bayhaqi no. 18268)

At some time, the breeze of Madinah Munawwarah as well as its soil emitted a delightful aroma. Ibn Battaal Rahimahullaah states, “Whoever stays in Madinah Munawwarah finds a pleasant fragrance emitting from its sand and walls." 
Ishbeeli Rahimahullaah states, “The soil of Madinah Munawwarah has a scent unlike other scents, in fact, it is something extremely extraordinary.”
Yaqoot Rahimahullaah states, “Amongst the specialities of Madinah Munawwarah is its fragrant smell. In the rain of Madinah Munawwarah, there is a fragrance not found anywhere else.”  (Wafaaul-Wafaa vol. 1 page 20)

The object of the first two stanzas is not to convey information, but to display grief and sorrow. The poet asks, “Is the shedding of tears due to thinking of those areas connected to Madinah Munawarrah, thus displaying one’s passionate love and fondness for Madinah Munawwarah?”

Rasulullaah SalAllaahu Alaihi Wasallam too had great love for Madinah Munawwarah.

Anas RadhiAllaahu Anhu narrates that when Rasulullaah SalAllaahu Alaihi Wasallam would return from a journey, and he would see the walls of Madinah Munawwarah, he would hasten his conveyance. (Bukhaari no.1886)    

Aaishah RadhiAllaahu Anha narrates that Rasulullaah SalAllaahu Alaihi Wasallam supplicated,

اللَّهُمَّ حَبِّبْ إِلَيْنَا المَدِينَةَ كَحُبِّنَا مَكَّةَ أَوْ أَشَدَّ

 O Allaah! Make Madinah beloved to us as we love Makkah Mukarramah or even more.
(Bukhaari no. 1889, Muslim no. 1367)

In another duaa, Rasulullaah SalAllaahu Alaihi Wasallam supplicated,

اللَّهُمَّ اجْعَلْ بِالْمَدِينَةِ ضِعْفَيْ مَا جَعَلْتَ بِمَكَّةَ مِنَ البَرَكَةِ

 O Allaah! Grant Madinah double the amount of blessings what You have placed in Makah Mukarramah.
(Bukhaari no. 1885, Muslim no. 1369)

Umar RadhiAllaahu Anhu used to supplicate,

اللَّهُمَّ ارْزُقْنِي شَهَادَةً فِي سَبِيلِكَ، وَاجْعَلْ مَوْتِي فِي بَلَدِ رَسُولِكَ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ

O Allaah! Grant me martyrdom in Your path, and let my death be in the city of Your Rasul.
(Bukhaari no. 1890)
